We bought this for our 7 year old daughter this summer and it is still working great. She loves this doll house! We also still have my original 1975 Barbie Townhouse (3 story), and it sits right next to this one. My daughter has been using the 1970's house since she was 4. I'm not sure the new one would have stood up to the usage of a 4 year old. It requires gentler usage than the old style.
We actually like the way elevator on the old townhouse is moved better, but this one is okay. However, the placement of the elevator on the new one is in a better spot. It doesn't break up the rooms like the old one did. There is a little stand in the elevator to help hold up the dolls, but it's really not needed and makes it harder to use.
We have had some trouble with the lamp. It is easy to put in, and easy to knock off with a Barbie head. Not a big deal. Also, would have been nice if the roof of the top level was solid and not lattice type. She can't set anything on top, it all falls through.
The shower was a big hit, not sure why. It just plays a short recording of Barbie singing in the shower. The kitchen chairs are a little flimsy, hard to make them stay upright when the dolls try to sit. But really, none of the Barbie furniture is that great.
The door is hard to use when the elevator is on the ground floor. Not a big deal, just move the elevator. Still, props for adding the door with doorbell. That was also a big hit. The actual kitchen accessories are great, instead of just background pictures.
Assembly was pretty simple - so were the instructions. So, if you need more than just little pictures you're going to be in trouble. But really, you can almost figure it out just by looking at the picture on the box.
This house does feel flimsier than the old townhouse. I doubt it will last until my daughter has her own children like my house did. The plastic doesn't seem like it will hold up that long, like the old particle board house. Still, it was a good buy and my daughter really loves it.
