We loved our time in Russian Hill. The apartment was really lovely and in a great location with restaurants, shops and cafes within a few metres. We especially enjoyed the organic supermarket on Polk Street and drinks in the wine bar at the top of the street, again on Polk. I went to The Pad, a yoga studio, 5 minutes walk away, each morning, which was also really good.
Back to the apartment - we are a family of four and the kids were able to have their own rooms, with one sleeping in the office/ single bedroom, which she (perhaps unfairly, but very excitedly) termed her "Harry Potter bed" under the stairs. Otherwise there were two good sized double bedrooms. Lots of wardrobe space. The kitchen was well equipped and it was lovely to have all condiments (and much more) provided for us.
We were out and about a lot, and enjoyed the comfort of the apartment and Netflix to relax with in the evenings. We didn't really use the back terrace, but it would be a lovely space in summer.
I wouldn't hesitate to stay here again, if we return to San Francisco. Highly recommended. Thank you.
