Three (very comfortable) king-sized beds, as listed. Great bedding; great shower; everything everywhere was very clean. We were there in the winter, but would enjoy the summertime, so close to the lake!
We did enjoy the basement fun zone: foosball, air hockey, mini-ping pong. There are Lots of board games, as well.
Not mentioned on the listing is that there is accommodation for infants: we used the Pack & Play and high chair. There is a stroller and a bunch of Duplos. That was great.
It's a bit smaller than it looks (although the listing does state the square footage). We were three adults and a baby and it was perfect. During the summer, people could enjoy sitting on the porch outside, (or the kids could play downstairs-- or adults :-). and there are plenty of chairs and stools if you were to eat inside with a group.
I try to travel with night lights, which came in handy, as the bathroom lights automatically turn on with fans. (-:
I'm very pleased we chose the Funcation house, rather than a hotel.
