33 by the sea was great!
Our stay at 33 by the sea was great! The room layout was perfect for our family as it allowed the kids their space and us some privacy. Very clean with everything that a family can need provided from dishes to towels and laundry. The pool and private beach were very nice. Prime location made it very easy to key hop to the upper and lower keys. Close to grocery shopping, restaurants, several activities and attractions. One of the highlights of 33 by the sea was sunset park which is 2 minutes walking distance. We've traveled all over the world and the sunsets there were top tier. We accidentally left some clothes and the owners shipped them to us. Definitely recommend choosing 33 by the sea.

Wonderful vacation spot
The condo is exactly as described and photos are also accurate. Having a great time! When we initially booked the condo for 2 weeks we checked to see if the condo was available for a 3rd week and when we found out it was we booked for a 3rd week. Our initial 2 weeks are over but we are very happy we have 1 more week to enjoy. Very nice, clean condo. Close to beaches and great pool. The 3rd floor steps take a bit getting used to. One negative is that the dryer on our floor doesn't work and while a new dryer has been on order we've had to use the dryers on the 2nd and 1st floor. All in all it's a great place to stay!

Just perfect
This was our first time in the Keys, and after trying to decide if we should move around a couple of times, I just booked this place for the whole week. Couldn't have been better. The apartment was absolutely spotless, tastefully decorated, and very comfortable. We enjoyed the little beach (others have said it's too small - I mean, it's 25 steps away! what do you want!), the pool, and walking over to Sunset Park for sunset. Easy trips to Sombrero Beach, Bahia Honda, Key West, and Islamorada - and also a couple days of not leaving the property at all. Slept so well I asked about the mattress - better than ours at home! Heed others' reviews about bringing quarters - $2 to wash, $2 to dry. Then you don't have to waste time chasing down quarters (though you can get them from the office during business hours).

Great Location in the Middle Keys
My wife and I quite enjoyed this accommodation, our fist time to the keys. The condo was spotless, airy and bright and had obviously seen some upgrades from the original fixtures (it's a 70's era building). The condo buildings and grounds are all kept and maintained. The beach is small but sandy and clean, we spent a fair bit of time lounging on the lawn and using the beach, although there wan't much natural shade (it was 88 degrees). Location is great - you are within easy driving distance of both ends of the keys, as well as a couple of municipal beaches and Bahia Honda State park. Grocery shopping (Publix or Winn-Dixie) was 12 minutes away on Hwy 1, liquor store beside the Publix. The only thing we missed was the view from the balconies (they are not very deep, view is mostly parking lot or next building - but better than looking at snow). You can't help that when you're the 3rd building from the beach.

Perfect home base!
My husband and I stayed with our 2 teenage kids. The condo was a perfect size and close to so many different things. We were there for lobster mini season and had a great week. The condo was on the 3rd floor and always had an amazing breeze off of the master bedroom balcony. We walked in the morning/evenings up and down the neighboring streets. Felt very safe. Be sure to bring quarters for the coin laundry-it’s just right outside your door but very quiet.

Our stay in Key Colony was perfect. This condo is in a quiet location, a clean property and right on a beach. The condo is very clean, kitchen has everything you will need and beautifully decorated. The beds were very comfortable and the AC works perfect! Just a very short walk to Sunset Park where we watched the sunset every night. We would highly recommend this condo.

Great location, enjoyed our stay overall. Main bathroom is not ventilated well and gets hot. Left note at the end of our stay via email about accidentally leaving food in microwave but never heard back. The three flights of stairs are steep and somewhat taxing even while not carrying anything. Mostly clean. Great private beach area with convenient shower and picnic tables under cover with grill and trash disposal area. Enjoyed the grassy area for cornhole in late afternoons.

Five Stars for sure. Walking distance to your private beach, walking distance to a beautiful public park, people walking, jogging, and biking on the road at the front of the property. Everyone we spoke to at the beach or pool were return customers. That's a strong indication that they're doing it right at Sea Isle. Our condo was exactly as described and exactly what we needed. It was perfect! I can't recommend this property enough.
