My Dad and I stayed at Cherie and Ron's place my last few days back visiting SF and it worked out perfectly. I think the main thing is that as an in-law you just have to know what you're getting into. The living room isn't big, but I was able to sleep on the futon there just fine while dad took the bedroom. And the bedroom is quite a good size so it was plenty big enough for keeping our stuff. I was expecting a much more minimal kitchen area as well but actually the fridge is a decent size (kind of medium I guess) and the stove does have four burners. I don't think there were a lot of pots and pans but again I don't know what people were expecting. They also seem to be continuing to improve things - for instance the wifi worked great.

Some things to note are just that the heat comes from upstairs so I guess if you were at the place for a while during the day it might get cold. But there are space heaters and it was plenty warm during evenings/morning and at night. Also, the family is upstairs so of course you will hear some running around, etc. Finally, watch your step leaving the bathroom! My dad had no problem with this but it took me a few trips.
