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.

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.

Amazing hotel, amazing breakfast. Only issue, which is not a hotel problem is the street noise, you hear the traffic and people walking past the hotel at all time during day and night.

I love this property; very serene, not a party vibe. Intimate. Private. Clean and beautiful too. Good breakfast, drinks / snacks available. The pool and grounds are so pretty. I had the key lime room, second time here to this b&b and it was lovely AGAIN. Will be a future visitor here again in the future. Walkable to attractions but still felt safe to me, as a solo female traveller this time.

My husband and I recently stayed at this charming and historical Queen Anne-style B&B. We especially enjoyed the delicious breakfasts served each morning in the beautifully appointed courtyard, with the calming sounds of the water fountain. The staff were always pleasant and helpful. The B&B's location is a big plus, with easy walking access to Key West's famous sites and museums, including the Hemingway Museum, Duval Street, and the waterfront. We found our room, the Audubon room, to be spacious, clean, and beautifully decorated with tasteful art works and tropical plants. We appreciated the large, updated bathroom with the separate bathtub and shower, and the comfortable king-size bed. When we reserved our stay, we erroneously believed, based on the photos on Expedia's website, that the room had a private sitting area exclusively for our use. Unfortunately, that was not the case, and this area was open to all guests and could disrupt the quietness and calmness of the property. Despite of this, we truly enjoyed our stay overall and would definitely consider returning on our next visit to Key West.

This was an exceptional B&B! It was so quiet and comfy and I felt so at home. ;Diana went out of her way to reassure me when I had some reservation issues with Expedia. The grounds are beautiful and peaceful and you get served a delicious home cooked breakfast in the garden. I highly recommend it

This house is absolutely charming and perfectly located. We were given the Papaya room which is not in the main house but in another small building in the back. You can have access to the house at any time anyways. The room was small but very clean and pretty. The property does not have enough parking spots but you can park across the street for free. You can relax beside the small pool, or in the beautiful garden area. Breakfast is served starting at 8:30AM ( kind of late for us) but as we had booked a snorkeling trip and need to leave early, we were given a bag containing yogurt, fruits and bagels which was very convenient. I would go there again, although the chicken (who roam freely in the town) kept us awake most of the night. Not sure if you can do better unless you book a more recent hotel better insolated...

The mermaid and the alligator is a nice property in a good location. Unfortunately because of its location it is noisy in the evening with traffic noise. Shower had mold on the ceiling. The room we stayed in had no tv and not enough electrical outlets.
