OMGoodness! This was a gift for our granddaughter for Christmas. She is 4 and little did we realize just how much fun she and her 7 year old brother would have playing with it. He likes to build and create and so he had a lot of fun assembling the beds, building the stairs and all. They love it! Highly recommend. The toy is well designed, sturdy, the wheels allow them to easy move it from place to place. Excellent purchase.
