First the good news: friendly staff, very well located for the Colma BART station and for access to SFO, attractive enough room, a few restaurants and markets within walking distance (though maybe better not go too far at night), and a satisfactory continental breakfast in a room adjoining the lobby. Now the other news: something was very strange with the WiFi. In our other (many) motels on this trip, no special problem; but with WiFi here, I could receive but not send messages from my primary ISP. Being too far from home to sort that out, it became inconvenient as the WiFi slowed down due to apparently limited bandwidth. In summary, the WiFi was free but not too useful.
The other thing was potentially more serious, a dispute between two guests in nearby room(s) between 1-2AM, to the point that we tried to phone the front office to sort it out. There was no way we felt safe enough to go out to see, or even turn on our light. But nobody answered. It got to where we wanted to get police to investigate but we thought this would make things even worse. The next day I asked at the desk. The person said they did not answer their phone because "we have to sleep sometime" but that they had in fact called the police, who came and evicted one of the two offenders. The staff member explained all this politely, and said it was a "rare event," but I'm not 100% convinced of that, and think there should have been some safe way to get some action from the staff or owners directly.
So if you accept that this sort of thing happens sometime, and that we lost a night's sleep because of it, and that the WiFi was behaving strangely, then just focus on the good things and take your chances. Without the domestic disturbance, I would have rated this 4 stars.
