Apoorva's place is awesome. It is right at the bottom of Bernal Heights and steps away from a bus stop. Its also the 14 an 49 busses which are some of the most frequent in the city. It was also a lot quieter than I thought with all the transportation around the area. The room is located away from the street. Apoorva was also a very responsive host and would reply fairly quickly.
Really the only drawback about the space was that the central heating is not connected to the guest room, so it gets really cold during SF winters. I was told to just increase the thermostat and leave the door open, which solved the issue, but it was kind of uncomfortable leaving the bedroom door open while sleeping at a stranger's place. But really thats just an issue that could be solved with a small space heater.
Other than that, it was a perfect place to crash while visiting SF. Highly recommend
