We used all five rooms in the house that is adjacent to the main home.
The house is well appointed and clean. It exceeded our expectations. Great location very close to Western Springs, MOTAT and the zoo.
Gang was really responsive and we were able to check in early which we really appreciated.
One thing to note is that in the house we stayed there isn't a lounge or kitchen, however the two bedrooms upstairs are very big so can easily accommodate your group as a place to gather.
