We stayed in this unit for 3 nights during our visit to SF. The location is great and was just a few minutes walk to Montgomery Station to catch the Bart. We were able to walk everywhere without issue from this fairly central location - Union Square, Ferry building, Pier 33, Fisherman's Wharf, Russian Hill, Nob Hill, Hayes Valley, Haight/Ashbury, Chinatown, Tenderloin. We only took the Bart to and from the airport and the Mission district actually and took a cab only one drunken night, but we may enjoy walking more than some.

The unit was very clean and exactly as pictured. Small, cozy but it had everything we needed and was very well stocked.

The street is quite noisy during the day as it's only the 3rd floor but once the window is closed it was very quiet and we didn't have an issue during the evening .
My only 'complaint' is that the murphy bed is a bit crickety, not as comfortable as I would have hoped for.

Momchil and Savina were very responsive and accommodating and that always makes using airbnb a positive experience.
