Beautiful B&B in Old Town. Choice of hot or continental breakfast — or both! Staff were friendly and helpful. Our Garden room was fantastic. If we make it back to Key West, we will stay again.

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!!
