Contrary to the critique of a Vorrezendenten but I do not find that the hospital is unstable. It is plugged together, which implies that you can also take apart the single element again. Who is a little rough when playing, then you ever can have the roof again in hand. But instability I could not find so far. As with all products from Playmobil is part of the hospital a lot of accessories. From a (miniature) ECG to the flower vase is because all there. A certain fine motor skills should be there already exist in a child. In my 5 1/2 year old daughter works very well; much younger she also may not be.
The durability of Playmobil products is very good overall. I bought the pirate ship me (oh God, how time flies!) Over thirty years ago. It still exists today!
My daughter has a lot of fun with the hospital. The various stations (children's ward, operating theater, patient rooms etc) allow that the child with almost all operations at the hospital can deal with.
