I’ve been going to Key West for 20 years - and stayed in many hotels this one was by far our favourite so beautiful romantic quiet, I loved the room and the four poster bed, the pool area was quiet and had a delightful view over the ocean, the breakfast was a good selection for all tastes! Staff very friendly and professional- I couldn’t recommend this place highly enough - we didn’t want to leave!
Beautiful, romantic location right on the water. Infinity pool overlooking the Gulf. We stayed in Bungalow 103 which was right next to the pool and had a view of the ocean. Room was great with kitchen and walk in shower. We will be back!!
The history in the house is rich. Even though it’s on the end of Dual it was quiet and we did not have a bunch of noise when trying to sleep or seep in. Breakfast in the morning was great.
Charming old home with history. Nice location right on the water. Very convenient cafe and bar on the property. Great location for strolling downtown Key West. Service was excellent. Very nice place to stay while visiting Key West.
our room and the staff were wonderful. we could not sit outside of our room due to a number of smokers. the same was true when we attempted to have a meal on the beautiful. we had smokers on both sides of us. i have health issues with my lungs and can not and will not stay at any ficilty that permits smoking anywhere on property. nowhere in the information provided by expedia did it mention smoking on property.

Very comfortable Victorian Mansion on the water. Calm relaxed atmosphere.
Room was great! The Balcony was a bonus that we were not expecting!
Staff and grounds crew were vey friendly and helpful. Had a great time and would definitely stay again.
Beautiful property in stellar location. Wonderful staff, excellent accommodations and above and beyond breakfast bar. Convenient to restaurants and shopping. Will definitely stay again!
Picked this hotel because it was adults only. Place was beautiful with a nice heated pool open 24 hrs. Breakfast was good too. The only thing was the bed was very sqeaky (not good for our romantic night). It also needed more electric outlets. I would stay here again. Plus it had ghosts. 👍
