I cannot say enough about how much I like the Tree House. My daughter is only 4, however, she is able to play with it just fine. She puts the dolls inside, they have picnics and she loves pulling coconut up the tree. I highly recommend it even though it is quite expensive and very large...the tree branches are removable though, so you can store it nicely.
If you are trying to create an American Girl town for your kid's dolls, this is a must have! It is a fun and unique piece to have.
