Tom's apartment is quiet and safe, the bed is comfortable (if a bit on the hard side) and the bathroom is clean. There's excellent wi-fi. Tom has coffee in the morning and a kitchen if you need it. It's a old building that's seen better days, but that's true of most residential areas of San Francisco.
I recommend this place, but with the caveat that parking in the area is very hard to find, day or night. There is a nearby public garage that charges $30 a night and $35 a night on Fri-Sat. You may be better off leaving your car behind and taking public transportation combined with Uber. If you're young and adventurous, go for it. Old out-of-shape fogies like me should just shell out more bucks for more convenience.
