We had a great stay at Mary’s place. The room was sparkling clean and the bed was very comfortable. As other reviews have stated, room 4 is up a very narrow staircase but that was no problem for us and Mary was quick to help with my luggage. The room does get quite warm but the patio allows a nice breeze if you can deal with the street noise. We would highly recommend Mary’s space for anyone traveling to SF! She even left us water and snacks which was so thoughtful and also leaves food for the guests in the kitchen.
