Small but it worked for what we needed. My wife had to work in the morning but with her headset, she had no problems with the upstairs noises. The location is very convenient to a whole different side of San Francisco.
If you like to be away from the city and close to the beach and the south side of golden gate park then highly recommend this place. So many great restaurants nearby, access to community bikes but more importantly the Muni station is a block away.
