Very pleasant beautiful B&B. Breakfast was so enjoyable. Room was wonderful and the bed was super comfortable. My only issue was the hot tub jets didn’t work and the grounds could use maintaining. Location was also in a nice quiet area.

From the very warm welcome by the reception staff we felt almost home. The room was very tastefully decorated, functional and clean. The highlight is truly the courtyard where you can have breakfast outside under the canopy of beautiful lush tropical plants or just relax at the pool. Breakfast is delicious including fresh fruit, fresh pancakes etc. when you are done with the tourist buzz in the rest of key west this is a very special retreat, quiet, shade / cooler and relaxing! Would highly recommend!!

Lovely accommodation. Staff really attentive. Love the quaintness of the gardens to sit and relax . Set Away from the hustle and bustle but only a short walk to Duval street. Love the idea of the snack station /drink station. Really lovely touch. Breakfast all cooked fresh and plentiful. Thank you would definitely recommend and study again if we were visiting the keys .

From the minute you arrive at this beautiful colonial style hotel you are made so welcome by the staff, we stayed in the Garden room which is small but beautifully made out and very private (don’t let the glass wall shower put you off you can’t be seen from the outside) the pool is a small dip pool set in lovely palm tree covered gardens and is like taking a bath, breakfast is served outside weather permitting and is freshly made and different each day, parking is limited but this didn’t seem an issue, the only criticism I could give is communication as we emailed the hotel twice several weeks before we traveled regarding the area and only got the standard auto reply and nothing else.
