Sam's place was nice and accurate in its description. Location walkable to Moscone Convention Center, though will agree that the homeless population residing on the street in front of the home was a turn-off.
We did have trouble with communication with Sam during our stay, which was quite problematic due to the lack of heating when we checked in. I contacted Sam the morning after check-in to let him know the heating would not turn on and it was extremely cold. We had 2 young children including an infant with us, and this was a significant concern. Sam responded and was aware of the problem, but simply stated the home would take time to heat. I sent several follow-up messages explaining that the heating had not turned on in 10hrs and requested a phone or video call to help troubleshoot but he would only respond by message every 2-3hrs. We finally got the heating on after hours of changing settings on the Nest, while our kids spent the day at a nearby restaurant, but no thanks to Sam.
