We stayed here in mid July with two family groups together. There is a fantastic bunk room, which the kids loved and a really nice big dining table which could seat us all comfortably. The location is really great, just opposite a little walking track that will take you into the shops via a recreation area.
Once you have the fire cranking, the whole house will warm up. If you're going to keep the fire going for more than one than a day you will need to chop up more kindling, and bring in loads of wood from the garage, so be prepared for that.
We really enjoyed our stay. The house is tidy, but not fancy so you can feel pretty comfortable with your kids running around.
