My 5 year old daugher loves it. It is wonderful to see her play with it for hours and hours. We mounted it in a corner of our livingroom. We mounted a few pieces on one wall and few pieces on the other wall. It has storage built in so all the little pieces can be put away after use.
This is such a clever idea - take it off the floor to the wall. They did this with the hot wheels and we love those so now our girls have the same advantage - more room in the room.
We really like our Polly Pocket Wall Party collection.
