My boyfriend and I stayed here for one night while we were in SF for a wedding. The location is great! We were able to walk to both the wedding (in Potrero Hill) and breakfast the next morning (there were lots of options close by). The room was clean and humble and had a small fridge which was helpful for us.
We didn't use any common spaces except the bathroom but James welcomed us to use the living room if we wanted to. The room is connected to the shared bathroom. Overall this was not an issue at all, however it did cause some disruption in the morning when multiple people needed to use it and we ended up overhearing a phone conversation someone was having in there...
James was very friendly and responsive to my messages!
