It's a room in their lovely home, but you use a side entrance into the backyard with your own key, and I appreciated Eileen's respect for my space and my privacy. She's sweet and professional, and the spread of fruits, muffins, coffee, tea and other snacks was much appreciated... as was the advil the morning after the wedding party. The bed is very comfortable, and the jacuzzi tub and high pressure shower in the huge bathroom were both delightful. Location was great, a 10-20 minute walk from Liberty Station, and a 40 minute walk from Ocean Beach, but on a hill in a nice residential area. You may hear the planes from the nearby airport - they didn't wake me up though. Also the poodle is a sweetheart, and didn't intrude (though I wouldn't have minded).
