Patrick was an extremely accommodating host, my partner and I visited for 4 nights, and were made to feel nothing but welcome. His apartment was beautiful, the room and private bathroom were just wonderful, and he was happy to allow access to the rest of the apartment (including the kitchen) if needed. He was always interested in how we were enjoying SF, but was never intrusive or over-whelming, happy to provide recommendations to fantastic local restaurants.
I travel to SF regularly for business, and would not hesitate to stay with Patrick again if I extend another trip, I felt very at home there and really was made to feel like I lived in the area for a couple of days. Couldn't recommend him highly enough!
