It's in a nice safe neighborhood, with a park across the street. As advertised, there is nobody on site to help you check in. It was not very complicated, type in the door code to get in, click the link to get the app that opens the door. It's virtually door restaurants and bars, which handy for dining, but also meant virtually no street parking. Go to the parking lot they recommend, seems best choice [no "in and out "], and walk to Coit Tower [about 3 blocks up a steep hill], 5 blacks down hill to Fishman's Warf, 7 blocks down to the ferry to Alcatraz. Remember downhill out means uphill back. The Original Joe's is 1 block south and kitty corner across the street. HIGHLY recommended, on the expensive side [$$$$ on a scale of $ to $$$$]], and VERY popular, so don't wait until the day before to make a reservation.
