We own this house. It was the big gift for my oldest dd the year she was 5...she is now 7. She and her sister (2...3 in Dec) play with it on a fairly regular basis and in fact at this point the younger gild probably likes the house more than the older girl.
I think it is a great toy. We bought a whole bunch of room sets to make the house more fun, but the stuff is well made and kid friendly...we have had no issues with breaking or anything falling apart and the items have not been gently handled. I have spent many hours playing house with both girls.
ToysRus often has a buy one, get on free special on this line of toys, and the year we bought for dd I actually bought our niece a house as well...so each house cost $25 - now that was a bargain!
The other good thing, this toy really holds it value well. I had originally planned to buy a used house on Ebay thinking that would be a better deal. Well, the prices for used were crazy (lots of grown up collectors who drive the prices up).
I actually found an older house at a yard sale and paid $1 for it. I cleaned that house up and I was able to sell it for almost what I paid for the 2 brand new houses! Kinda crazy! Anyway, once dd's are finished, I have no doubt I will easily make money on the house when I sell it.
