Practice rooms in SF
Does anyone know of music practice rooms in the City proper, available for affordable hourly rental? I need: (1) enough space for two musicians; (2) classical-friendly space (i.e. wouldn't want a rock band blaring loudly in the room next door); (3) minimally decent-sounding piano included in space; (4) open on weekends. It'd be nice to find something in a neighborhood where parking is possible, but downtown is doable as well. Thanks!
