Carol's apartment is directly on California St. - the living room and second bedroom open up to a small patio that is separated from the sidewalk by a fence. The sliding glass doors let a lot of cold air & sound through: you can hear the CalTrain pass by as if you were on the tracks. The heating system itself is also very loud, so you must decide between being warm or sleeping in peace, though the later is hard even without heat as the street noise carries.
Otherwise, the living room and kitchen are functional, the bathroom is well-stocked, and it's a quick stroll to Castro St. or the CalTrain station.
