Pros: Wonderful host, Vincent will be extremely nice, and be available to solve any issue you could have. The room is extremely clean, well furnished, beautiful bathroom, very comfortable bed. Neighborhood is very quiet and nice, close to the heart of Noe Valley but also close to Castro, so close to lively spaces. Vincent provides a fantastic set of snacks to compensate a little bit the lack of kitchen.
Cons: it's only a room + quite dark (perfect for a tourist who should not be spending too much time in in the place, complex for a business traveler as there is not even a desk where one can work from). A little expensive for the size and amenities the place offers (no kitchen, no living room, etc.) in comparison to the rest of SF.
Would recommend the stay, mostly if you are visiting as a tourist! You'll be greeted by a wonderful host.
