Larry has been a great host through my month in SF. Everything was arranged when I got to the house even though it was pretty late. He was also very prompt to answer my questions.
The room doesn't have a window (which I knew from the start) but appart from that it is really nice and it doesn't feel like it when you're in it. The house is very quiet and with plenty of space to hang out in the living room or to cook.
The neighborhpod is really nice, a few blocks away from everything you need and close to the bart and the 14 that will get you to the heart of San Francisco in no time!
