Fairly simple adventure, arrived late, unpacked, showered, hit the town for sunset, got in late, woke up early, had breakfast (little underwhelming for me), packed up and left! Lady at reception pointed out a free place to park a few blocks away which was appreciated :) Would definitely recommend.

This is an amazing place very well situated just off Duvall Street and close to the beaches, room was excellent and staff very friendly apart from the ladies at the bar who were rude and unwelcoming

Lovely quiet hotel
Lovely hotel in a quiet neighbourhood just off Duval St. Very welcoming, lovely room, great shower and lots of loungers and towels available by the two pools. Only slight negative was the breakfast, which was a bit limited to pastries, waffles, toast and cereals - some fresh fruit or yoghurts would hVe been appreciated!

Good 6.0
3 star trying to be a 5 star
Paid $400 a night. $35 for parking for 1 day. $25 resort fee. No pool bar. Too much chlorine in pool bleached my bathing suit top and turned my sterling silver necklaces black. Could not check in until 4. Wifi down. Could not give us key cards until 8 pm. Gave us a warm bottle of white wine for our troubles. Room so small 2 people can not fit in bathroom or barely walk around the bed. Way over priced. Did not have their breakfast. Stay elsewhere. Desk ckerk made sure we knew he just worked there.

Original room was very small, but staff was very accommodating and moved us to a much nicer, larger room.
James, us4 night trip with friends
Fair 4.0
Lovely property. Uncomfortable room.
Bed was incredibly uncomfortable and creaky—every little move was enough to wake each other up. The room was also one of the “loft” rooms and felt really small and short in many places. The other guests on the floor were also incredibly loud-it seemed like our floor was where they would put groups and they would shout back and forth across the floor at night. On the morning of our final stay, a fire alarm went off that was so loud in the room as to actually be disorienting—the opposite of what you want. The outdoor area of the property was beautiful. We enjoyed the hot tub and the service at the establishment.

No Room A/C Control was a bummer
I have never been to Key West before, but the one thing I did know is that most places are small. With that in mind, I made sure I booked a bigger room. Our room was on the second floor and even though it had two rooms, it was small... but the perfect size for us. The only issues we had with the room were the pillows (a bit large and lumpy), YOU CANNOT CONTROL THE A/C IN YOUR ROOM, and our room faced the pool. The pool issue is not normally a problem... until people come back from the bars and decide to use the pool at 2 a.m. Regarding the pool and hot tub areas - I imagine they are nice "in season", but the small pool was not heated and the bar area by the pool, that they show in a lot of their photos, was closed. Matter of fact, they had a bunch of old mattresses stacked up out there. So much for the romantic, relaxing time out at the pool. And I'm pretty sure there was no refund on my bill for that (tongue firmly in cheek). Plenty of towels out at the pool and everyone we ran into that worked outside was extremely nice. $28 a day to park is a drag, but if you were to stay in Miami at a hotel, you'd be paying for overnight parking too. We parked at one of their spots off-site, but it was only a couple of hundred yards away. We never ate their free breakfast, but when we walked though it looked like a nice setup. Make your own waffles, fruit, juices, cereal, and coffee. If you want to save money on breakfast, you could eat here no problem.
