We spend 4 days in Richard's condo. And to be honest, everything was perfect. We came a bit late for the check-in, but Richard was waiting on us, took time to explain everything we need to know about the apartment and the city. The location is very nice: 5 minutes walk to Market St. and from there you'll have all the public transportation.
The apartment look exactly like the photos. It's spacious and you'll have everything you need in it. It's also very quiet even if you're in the center of the city, so you can have a restful sleep. If we come back in San Francisco, we would like to stay in this condo again.
