The property is a beautiful oasis and the staff kind and accommodating. Good location if if you don't mind walking a little and easy to get Uber if preferred. Breakfasts were exceptional and our room/mini-cottage was beautiful! I highly recommend this property and hope to be back on our next visit.

Loved the property, great breakfast and amenities. Rooms could really use tvs to keep up on weather or local events happening. I'm not a big TV person but do enjoy watching local news and world news and weather. Like to do it in privacy.

I was honestly blown away by this place! The backyard is truly an oasis - I could’ve sat there all day and have been perfectly content. We were in the Sun Room, it was so cute we definitely want to book the same room again! It was really nice to be able to park at the residence, as another we stayed at required us to park at paid parking. Highly recommend!

As a light sleeper I was worried it would be too noisy since we were in the Garden room right off Truman, but it was totally fine. They also provided a white noise machine for super light sleepers. The free breakfast each morning was nice- good variety day to day and filling until lunch. The location is walkable- made for sweaty walks due to the heat in late May, but we loved walking because it helped work off all the key lime pie! The B&B also had a small fridge constantly filled with cold water bottles, which were a godsend for all our walks and to keep hydrated while out and about. We easily walked from the B&B to Mallory square in under 30 min. There are also tons of bike and golf cart rental places nearby so it’s easier to go downtown if you like. All in all a very chill, quiet, and serene place to stay. Felt more personal and historic than the large resorts/hotels closer to downtown- a nice place to retreat at the end of the day after being out on the water or exploring downtown Key West. Would totally stay again!

Really wanted to absolutely love this place but it definitely needs work. Stayed in the Sun room, the bathroom has absolutely no ventilation so it turns into a swamp every time you shower. Theres a window in the bathroom that does not open. The bathroom also had a strange smell. My husband opened the the cabinets under the sink and it filled with water and dead bugs. He did this on the morning we were leaving so we didn’t have time to complain. Housekeeping daily is a great amenity to offer but like they dont even vacuum its just the bare minimum. Breakfast didnt taste bad but its cheap and bare minimum. Im sorry but this bed and breakfast is not luxury at all in my opinion. The location is great and walkable to Duval Street. The outdoor dining area is beautiful. Im sure there are worse places to stay just lower your exceptations if you are staying here.
