I had a wonderful stay at Ruben's apartment in San Francisco. I was there for a conference and the location was ideal - 10 minute walk from union square and with everything I needed right on the doorstep. Ruben and Teresa accommodated me for a 30 minute early check-in and an hour extra on my checkout in order to allow me to meet my conference schedule. The apartment is clean and modern despite being in an older building. It is really quiet at night as it is at the back of the building. Thanks for a great stay.
