What do you like at a vacation condo?

Measuring cups, tea/koolaid pitcher and hair dryer

All of this!
Nice towels and linens are wonderful, good pillows and easy to find things.

There is a pea with a lovely cabin in tn that we've stayed in a few times. I love her local recommendations and list of 'rules' totally written in her voice.

Try bowls of white vinegar to absorb the smoke smell maybe?

Also, no air fresheners/strong scents that can cause migraines.

It sounds wonderful!

Coffee machine with filters, salt pepper, spices, dish soap, tin foil, plastic wrap, tupperware type containers for storing leftovers, corkscrew, fans in the summer unless there is air conditioning. It's nice to have a TV and something to play netflix although it's also nice to get away from that. Board games, puzzles, books, cards.

Our lake place is more like a second home, rented only to family & friends.

We supply linens, towels, & beach towels. We have wifi (no tv), board games, Lego, cards,a keurig, paper towels, t paper.

Basics for food, oils, vinegar, salt, flour, sugar, ketchup, mustard, mayo.

Because we do lots of entertaining, we have 2 gas grills, one outdoor gas burner (for corn on the cob or lobster), lots of nice pots, pans, utensils.

We also have a kayak, canoe, & floats & hammock.

I've stayed in a fair number of beach houses, and some of my favorite items have already been mentioned. A few others I thought of are:

+ a small washer and dryer, if it's not available elsewhere within the condo community
+ hooks on the backs of the bathroom doors! (pet peeve of mine)
+ pot holders and trivets
+ broom & dustpan
+ a few jigsaw puzzles, simple/classic board games, & deck of cards in case of bad beach weather, bored/sick/sunburned kids, etc.
+ a few classic movies and/or books (same reasons as above)
+ listing of local TV channels and how to access guide/menu
+ extra blankets + pillows for the inevitable person stuck sleeping on a couch, LOL

We rent a beach house every summer. I am particular about my creature comforts so I bring everything essential to my happiness. I bring my own linens, pillows, towels, beach towels, travel size Keurig. If I got to a place and it didn't have 100% cotton sheets, I would be unhappy at being uncomfortable for a week. I bring my own duvet and comforter because I worry that a rental washes their bedspreads as often as hotel, which is never.

I always bring my own freshly sharpened knives because I've never found any at a rental house that were anything but an ER visit waiting to happen. I bring my dish brush with a soap-filled handle because the sponges usually present skeeve me out. I bring my own paper products because my past couple of rentals have been lacking tp and paper towels. I bring my own trash bags because the ones supplied are often cheap and flimsy.

The thing I loved most about our place last summer was a huge closet with plenty of hangers. I have to have air circulation in addition to A/C so a ceiling fan is nice, but, yep, I bring my own fan in case there isn't one. 

A hook or hooks on the bathroom door is good. 

We have friends with multiple weeks of timeshares, and these are things I always like when we stay with them.

It's nice having enough extra dishes so that I'm not constantly washing them. I'm on vacation dang it, I don't need to be washing dishes five times a day! Since we stay with our friends frequently in adjoining units, it's nice when each unit has a laminated list of what should be in each of the units mounted inside a cabinet door (8 plates, 8 bowls, 8 water glasses, etc.) so we can put things back where they belong and a list of what to do with used linens and trash at the end of the stay.

One thing that is almost never there (but I wish there was) is a roll of aluminum foil, that self sticking Glad plastic wrap, a box of assorted sizes of Ziplock bags. We always end up scrambling around looking for something to store leftover cooked food in without using up the four plates or whatever there is.

It's nice to have a DVD player or cable tv, something with shows that kids can watch when they get bored or adults can watch at night if they're stuck there after the kids are in bed. WiFi is great too for downtime when you're done being outside or have had enough sun. If there is cable, some way to tell what's on when, and which channels are which. 

Washer/dryer access is critical, especially if you're catering to families with young kids who are constantly spilling stuff on their clothes, getting wet or dirty. Plus being near the beach, it's nice to be able to throw swimsuits and towels in the dryer so they're dry the next time you want to put it on. (There is almost nothing less fun than trying to wriggle into a cold, clammy, wet swimsuit even if your goal is to go swimming.)

It might be nice to have a life jacket sized for an infant or a little kid, since not everyone owns one. We have at least four child sized life jackets and two infant sized jackets that we keep at our lake cabin, in case people with younger kids come out to visit with us, plus a bunch of various types of adult sized ones too. People who don't spend a lot of time on or near the water don't tend to have their own.

A small vacuum for cleaning up crumbs around the dining table or sand that gets tracked in.

Extra blankets for those who get cold easily. Extra pillows with varied firmness (I particularly love it when there are extra soft feather pillows).

A binder with all the menus for local places to eat, and a laminated map showing where they are and how far away they are from the unit. Also a listing of other common places people might need to go such as a drugstore, Target, grocery store, gas station, post office/place to buy stamps and postcards.

Power strips in the bedrooms so people can all plug in their phones or tablets at night. I hate having to fight over who gets to plug their junk in when there's only one outlet in the whole room and there's already a lamp and alarm clock plugged into the two available outlets by the bed. 

Batteries for the remotes.

At least 8 plates and bowls, 12 would be nice. And make it Corelle.

We look for dishes, pots and pans and all necessary eating and cooking utensils. We rent a condo at the beach every year and the first year we went we went to make pancakes and there was no spatula to flip them. I had to run to a local store to buy one, it wasn't a huge deal and now we take one every year, but they had everything but that. I don't mind bringing my own bath/beach towels and bed linens. Having garbage bags would be a plus as well.

I love having a table with a lamp next to the bed.

It surprises me how some places don't even have a good lamp next to the couch or an armchair. We read more than we watch TV.

I also love to find a wall mounted magnifying mirror in the bathroom (or at least have a mirror somewhere with good light where you can get close enough to put your makeup on).

When we rent a vacation place, it's always fun to see what games and books have been stashed there for the guests. I always appreciate a hand-out listing the places the locals like. Our favorite place to eat at the beach is a little dive we would have known about. The food is fine, the prices are amazing and the owners are lovely people.

For it not to smell - no smoke, air freshener, etc.
Enough linens, dishes, silverware, pots and pans and utensils.
A Keurig would be nice - we could bring our own pods - it was annoying to have to buy a can of coffee the one time we rented a house.
Basic staples - basic spices, sugar, etc

We rent a beach place for a few weeks every summer. Towels, towels, towels. You cannot have too many. Hooks where you can hang wet things to dry. An outdoor spout where you can rinse things before coming in to the house. A dryer that dries efficiently. There is nothing that throws a wrench in my style like a tiny inefficient dryer that takes two hours to dry four towels.

Pretty much everything else is not that important to me. Cheap pots and pans and plates and silverware are totally fine (as long as there is enough for everyone). If kids will be among your guests, it is nice if there are some inexpensive outdoor toys (buckets, balls, frisbees) and basic indoor games.

Me too!  I thought I was an over packer, but maybe not!

Besides everything listed, we like to have an iron and ironing board. Clothes are extra wrinkly when packed in a suitcases.

Also a crockpot is handy to set up a meal in the morning. It can cook while you're out and about during the day exploring.

Kitchen wash cloths, hand towels, dishcloths to dry dishes.
