Location is excellent! We walked to Fisherman's Wharf/Pier 39 area, Golden Gate Bridge/Presidio, and to the Ferry Building. Over the first 3 days, we did log about 40 miles, but we wandered quite a bit. Easy bus line to get to the BART, which we used to go to an Oakland A's game. We came back on BART from the SF Giants game as well.
Coming in we used BART to get from the airport to Civic Center/UN Plaza, which was a short and inexpensive Uber ride to the place.
Great communication, and the place is well kept.
If you want a great breakfast, New Place on Polk is 2 blocks away and was VERY good!
