I had the opportunity to stay at Andy's for several months while completing an internship in the city. Both Andy and his roommate were very communicative and responsive, and the apartment is exactly as advertised. I really enjoyed the natural light in the apartment as well as the really comfortable bed/mattress.
The location was even better than I'd anticipated, within walking distance of the MUNI, convenience/grocery stores, and many restaurants/cafes/bars in the Castro area. I also frequently walked to Dolores Park (~20 min away).
The apartment is really great value for its location and amenities. I highly recommend staying here if you have the chance!
