My sons are aged 8 and 4 and they have loved this toy. I really like Playmobil because of the level of attention to detail that's put into the design. This boat was easy to put together (more so than other Playmobil toys we've had) and is very robust (it even goes in the bath!).
This set comes with four people, life jackets, an inflatable mattress, even food and plates and cutlery (which pack away under the beds when the boat is out on the water). There is a tiny sink with a tap and even a toilet with a lid that raises and lowers. There are four beds. The anchor goes up and down (the one flaw I've found with this is that it doesn't stay on the rope very well). The top of the boat lifts off so that you can get at what's inside.
My boys have spent literally hours playing with this set and it's so nice to see them participating in imaginative play rather than slumped in front of the television!
One other thing that impresses me about Playmobil is their customer service. We bought the airport set last year and one of the suitcases wouldn't close. I emailed Playmobil and within a week a replacement part had arrived in the mail, beautifully packaged.
