This was a great place for our 3-night visit to the city. The location was very central; it was easy to take public transit to most destinations, and we walked to the Mission, SoMa, and City Hall area. We wanted to try Blue Bottle Coffee and Tartine Bakery and both of those are within walking distance.
Trey was a great host and was very communicative leading up to the trip. The room itself is very cozy with everything you'll need and more. They had a lot of useful maps and books about the city which were fun to read during down time. The kitchenette was well-stocked though we didn't use it much. The one thing to be aware of is that the sound from street can disturb your sleep, especially if you like sleeping in, but ear plugs were provided and they worked just fine. Trey also let us drop off our luggage before check-in and past the check-out time, which meant that we had more time to explore the city!
