The short Version: 5* in each category.
The more detailed:
Nice apparment in a residential area between SFO and downtown. K/T light rail or Bus Nr.8 brings you downtown in 30 to 45 mins (2.50 $ using the Muni App), depending on where to go. The Stop is just 5 walking mins away. Appartement was Clean and all essentials like linen and towels are provided. The communication with Wilson worked out perfect (he doesn't live there) and self check in (Key Box) is easy. I can highly recommend Wilson's Appartement instead of any (expensive) SF Hotel ! Great address which I'll keep in mind when travelling to SF again !
