I cannot recommend Susan's place enough! It is a fantastic location, just 3-4 minutes from the beautiful views at alamo square. With the 5 bus you can be on market street for the muni stations in no time (or you can walk). The room is small but comfortable and cozy, and the house is really well stocked with everything you could need. I didn't have any issues with the bathroom (there is one bathroom for 4 guests but 2 separate toilets). highly recommended!
