We were pretty self-sufficient (frequent SF visitors) so we didn't bother Larry with questions or requests, but he left us almost daily messages that let us know he was available if anything was needed.
The space has a bit of a boarding room/hostel feel to it -- a handful of rooms along a central corridor, with a nice shared kitchen. You may bump into fellow travelers in the hall, and your neighbors could potentially be heard if they are noisy, but we did not experience any unusual noise issues at all. It's an old house with wood floors -- you'll hear people walking on the floor above you, or walking down the hall. But it doesn't seem like a "party" house, so everyone settles in at a decent hour.
Comfortable bed, etc.
The neighborhood is lovely, walkable, has great food and coffee options, and is convenient to major Muni stops.
