It's a very nice appartment well decorated with a large livingroom very cumfortable. The self checking is really easy. The situation is not far to all the tourist points of interest (15 min to the Mole and Chinatown, 30 min to Fisherman wharf and Pier 39 or Russian Hill with MUNI bus)
Everything is clean, the beds are cumfortables, you have place in the bedrooms for your bagages, the kitchen is well equiped and the place is quiet to be able to sleep in peace.
Nick is reactive when you need something or if you have questions. I went with my 2 sons during 4 days and I think it's a very good compromise to discover San Francisco !
