I booked this flat for my parents/their friends during their recent SF visit. My mom's review is below:

Four of us had the pleasure of staying five nights at 1144 Broadway in Russian Hill. What a lovely apartment! It is spacious and decorated, with a full kitchen in the event you want to cook. Kenji, our host, was there to greet us, and served delicious green tea while he went over all of the details of the city. He could not have been nicer. We won't be staying in a hotel in San Francisco anytime soon! I only hope this flat is available next time we visit!
