This was a great place for our group of 4 business colleagues to stay. 2 of the rooms had ensuite bathrooms & 2 rooms shared a bathroom, which was fine. The location is terrific-- up Powell Street, just before you reach California. The cable cars come rumbling by all day/night, which adds to the charm but, warning, it can be difficult for light sleepers (2 of us needed to pop in ear plugs but that was ok).
Valentino is a little slow to respond but he's a person of his word & was accommodating when we wanted to check out an hour later & even when we had some difficulties with the hot water he attended to it immediately.
A few things to note: there are NO TVs in the home whatsoever. We'd hoped to watch the presidential debate but ended up live-streaming it on our computers (there is high-speed wi-fi). The home wasn't ready at the time we specified so there was a bit of a wait. There were also a lot of items left in the fridge & I'm not sure if that was for convenience or it wasn't cleaned out.
Otherwise, great place, nice stay, excellent location. Just be prepared from some street & cable car noise.
