The photo's of my bedroom were very true to what was shown on Maria's page. She was quick to respond to any question's I had, and is a lovely person overall. When I was looking for a place to stay during my trip, I didn't want to spend the money that a decent private hotel room charges in SF. So instead of booking at a hotel with a shared bath, Maria's house offered a much better experience in a well taken care of home at a reasonable price.
Once suggestion if you are interested in renting a bike: I recommend walking to The Bike Connection (which is 1 block from Maria's) and renting a hybrid bike for a full day with lock and helmet for less than $40. The staff at this LBS are very friendly and take care of you. SF is a fun city to bike in!
