I travel to SF for work frequently, and this is one of my favorite places I've stayed. Jeff's studio was clean, well-appointed, and comfortable. The small kitchenette was well stocked with pans, etc., and was super convenient. There are lots of thoughtful touches throughout. Jeff was a communicative and friendly host.
The studio is easy walking distance from great restaurants, and about a 20 minute walk from the Design District where I work. I will definitely be looking to stay here again the next time I'm in town.
