Our stay at Mark and Sarah's place was great. The accommodations and amenities were very nice - we stayed in a lower floor suite with its own bathroom that was accessible through two separate staircases. One of the stairways was a bit difficult to navigate. There was a space heater provided in both the room and the bathroom alongside standard amenities. The location was convenient, about ten minutes south of many popular tourist destinations like Pier 39, the Ferry Building, etc. We had a good time!
