The flat was exactly as described. Very convenient location. We went almost everywhere by walking (except Golden Gate Park). Kenji was very helpful and took the time to give us lots of good information on the day we arrived. Kenji lives in the same building so it was very convenient in case we had any question.
Lots of services provided : sheets, towels, coffee. We were there with 4 adults and 2 young children and the appartment was perfect size for us.
I would defenitely recommend Kenji's Flat for your next trip to San Francisco.
