The Frog tree house has two levels. On the main level there is a double bed and in the loft there are two full size twin beds. This tree house is private and located on the front part of our property, closest to the road. Children love the experience of sleeping upstairs in the tree house where they will be close to you, under the same roof, but with privacy. When necessary we can add a small mattress to the loft for one additional child.
