My wife and I were looking for a private place during our 2-week visit to our grandson in SF, and it turned out that Maria's place was ideal. The room has its own street entrance and is separated from the rest of the house. The location has easy access in the city but remains quite. Maria was very thoughtful, and she checked in shortly after to make sure we had everything we needed. It is also worthwhile to mention that there are plenty of public street parking adjacent to the house.
My only suggestion for improvements is the bed mattress. The present foam mattress is too soft and has not enough support on the edge. But overall we had a very good experience in Maria's place.
