The house was clean. A major plus for us was that they had set up well for the kids in our group-- a helpful safety gate and two high chairs were available. Also the furniture was pretty sturdy and kid-friendly; coffee tables were round, stable, and low to the ground.
The quality of the house (mostly the bathrooms and kitchen) was really not as nice as the photos made it seem. For a house that contained so many bedrooms there really was no central place where everyone could sit to hang out. The wifi was very spotty. Kitchen could use a few more large pots and pans. There were a couple maintenance issues (lights not working, room that spontaneously locked itself), though they did address these quickly. The house is on the side of a highway and next to a construction site-- Noise level was ok but there is no way to walk anywhere from the house.
