We gifted this for our 4-year old for her birthday and she is absolutely loving it. Assembly took about 1.5 hours, and it was fairly easy to assemble; although my husband used a drill which likely sped up the process. The furniture selection is great. We could have used a few more pieces, so we have purchased additional pieces. My daughter uses her "Little People" in the house. She has been using it every day since her birthday. I also like the feature of the hinged section which makes the house more compact. I am sure this will be utilized for many years to come by all of our daughters.
