I stayed at Eric's place with a friend for 11 days and we really enjoyed our time there. Eric was out on a trip for the duration of our stay, so we never got to meet in person, but his roommate was really friendly. The toilet was one of the stand-out highlights for me, as it was decorated with carded Star Trek figures (as well as others).

The surrounding area is really nice and easy to reach through three bus lines in the area, lots of cafés and two bigger supermarkets in the nearby area.
Golden Gate Park and Haight Street and Alamo Square Park are all within walking distance, too. If I'll return to SF, I'd stay there again.
