We had a wonderful time in SF, not in the least because of the excellent stay at Irena and Greg's place. The location is great: near Chinatown and within walking distance of Fisherman's wharf (15 mins tops). Besides the location, Greg was a brilliant host. He had tips about restaurants, bike rental and sightseeing: all great. He even gave us advice about the next stops on our trip. An absolute wonderful first experience with Airbnb.
