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!
