We recently stayed 10 days at Kenneth and Bechara's home in The Castro.
The basement apartment is very comfortable, quiet and private, looking out on a beautiful back yard. The place was very clean, and there were plentiful linens, blankets and soft towels. The kitchen features a Keurig coffee machine -- which we made great use of -- a refrigerator, hot plate, toaster oven and microwave: perfect for a relaxing breakfast before heading out to explore the City each day. There were also provided some tasty snacks and several bottles of water.
Kenneth and Bechara respond almost instantly, and cheerfully, to any questions or requests. Check in was very easy and we were greeted with a table spread with brochures and personal reviews of local restaurants and activities. And, to top it off, a nice bottle of rosé to welcome us.
Highly recommended, and will likely stay here again next time we visit San Francisco.
