The house worked well for our family. We did have a couple of incidents with our taller son's hitting their heads on some of the really low doors in the house...after a few times, they paid more attention and it wasn't an issue.
I am not sure if there have been cats in the house or just because it is an older home, but a couple of our kids had horrible allergies while there.
The house is clean, they provided infant seats / high chairs for our little ones, and had toys for the kids to play with. The host was great. All in all, a great experience.
