Our kids really appreciated the yard, as it rained nearly the entire time we were there, and we weren't able to get out much. Every time the rain let up slightly, they headed outside to play ping-pong or badminton, ride in circles on the scooter, or swing in the hammock or porch swing. We ate most of our meals out at the picnic table, which was well-covered by a huge umbrella. The younger ones also enjoyed feeding 'Little Shark' the goldfish.
As far as beds, linens, dishes, etc. I think the house is really better suited to seven people than nine. There was an inflatable double mattress available for persons eight and nine. There is a dishwasher, which I assume worked, but no microwave. We were very pleased to discover that there was actually a second toilet, which I think was mentioned in the description I didn't see but not included in the quick summary section.
The house is fairly close to the train station, but we found that train tickets were quite expensive, so it would probably be best to have a car if you want to get out and see things. Also, you might want to look into what is available in the area. While we were there the only grocery store in town was closed 'until a new arrangement could be found' or something to that effect.
This house is quite child-friendly if you are comfortable being around other peoples' stuff. The family seemed pretty-laid back and said (in a note) that we were free to use whatever we needed in the house.
