This house has kept my 4 year old daughter entertained from the moment it came out of its box. 
It took about an hour to assemble and some of the parts felt a little flimsy until they were put together. Once built is it quite sturdy.
The house is absolutely huge so I would recommend you make sure you have space for it to live because once it's built you can't fold it away! Also being a 360° it need to have space all around it. Being so big does allow your child to be able to play with it as they grow so you should get your moneys worth! 
It doesn't come with any dolls so definitely worth making sure you have a couple for instant play.
Overall it is a brilliant house and will provide many hours of entertainment for my daughter.
