I stayed for several weeks before I found a permanent apartment in San Francisco. It's a very bright and sunny place! FYI it is a studio apartment so the couch is understandably small (you cannot lie down sideways on it).
The bed area was actually better than the pictures showed at the time (there were bookshelves, bedside table, headboard in the apt which don't appear in the pics).
He's very generous with making his kitchen available for use, many utensils, nice coffee machine etc etc. Would highly recommend this place - and the location is really safe and nice!
