Mary Clare's place was perfect. This was mine and my wife's first time to California and we started our trip off in San Francisco. When it was time to head south we didn't want to leave. We arrived and the room was remarkably clean, and there were snacks, fruit, and some delicious beverages waiting for us (all of which became very useful during our stay).
Prior to our arrival, Mary Clare gave us some suggestions for places to go/see that might be of interest which helped us out a lot! She was very quick to respond when we had questions and did not hesitate to tell us places to go even without us asking. She told us about the farmer's market just a couple blocks up from her house that she thought we'd be interested in, and even gave us some tips on the best fruit stand and pastry stand (you won't be disappointed if you are here on a Sunday and can make it to the market).
The neighborhood was very quiet and a great location; we felt safe walking at night even though we didn't know the area. We will definitely stay here again when we come back to San Francisco.
