We spent 6 nights at Ellen's place as a family of four, and it was a wonderful solution for our stay in SF. Located in a very quiet neighborhood, still, two blocks to all direction you have a bus to a central location. GG Park is by foot - of course the Park is enormous, but we walked all the way to the CA Science Academy.
Although there's no actual kitchen, you still have all the necessary amenities, just without the sink. It's actually more comfortable than some real kitchen's we had in other Airbnb's.
It is apparent that the apartment renovation is very high-quality, towels are fluffy and the beds are comfortable. There's even closet space for your luggage which is really nice to have!
Check in was a piece of cake and Ellen was an attendant host when we needed her! Highly recommended, excellent value.
