Guest reviews
9.2"Fantastic experience at an iconic Key West landmark!"
Aside from the beautiful architecture, history and perfect location (beach + Duval St), the rooms are clean and elegant, and the service outstanding. Elia gave us a great check-in experience (so helpful after a long drive...). Special thanks to Dean, who gave us a fantastic tour and took wonderful care of us during check out :) We will be back!!

The most gracious and professional and pleasant staff and lovely experience. The historic house, large rooms with high ceilings and location on the south end of Duval is ideal for quiet relaxation. We loved the sunrises and sunsets bottle from the warm saltwater pool deck. Outstanding breakfast of fresh baked local pastries and fruits.
