When we visited (December 2015) it appeared that the entryway to the unit was under construction, which was organized but still somewhat dusty. The unit itself was clean enough, but could have used another quick once-over. The beds are comfy and there is a Roku for tv entertainment. The owner lives upstairs and left some toys for our kids to play with and was really cool about walking down some extra towels when we needed them. From time to time we could hear the owner's children running upstairs, but given that it seems their kids go to sleep around the same time as ours, around 8 at night, the stomping didn't bother us and didn't impair our sleep. One other minor thing is the parking. We were lucky one day to find a spot on the street a few houses down the street but the other two nights we had to park a block away. Not a huge deal, but just be ready to double-park while you load/unload your luggage and family. It's also not a big deal given that a hotel in the city will normally charge easily ~$40 per night!
All in all, it was a good stay for us. The price was great and was located so close to Golden Gate park, you can't beat it. Also, the biggest perk for us was the included free admission to the California Academy of Sciences, for the whole family! This saved us, a family of four, a bundle!
