We stayed at Mark and Sarah's for a week to explore Potrero Hill during our move, and loved it. Mark and Sarah are very thoughtful, courteous hosts who gave us plenty of space, but always made sure we had what we needed; when I mentioned that the bed was a bit soft for my liking, they offered to and ended up flipping the mattress same night while we were out! The room itself is on a separate floor from the shared spaces, and provides for a lot of privacy. The shared living room has amazing views of the water, and street parking is plenty and super easy to find. Mark's place is within 2 blocks to most of the restaurants in Potrero Hill, and a short walk to the Dogpatch. All in all a great stay; highly recommend!
