We saw many different things in Amsterdam, but the most amazing one was Peter's houseboat. It's a fantastic experience, out of the ordinary. The houseboat is really close to the central station and basically to the center of the city (you can reach it in 10 mins) and here you can find anything you need. The house was very clean and Peter has been very kind to us: punctual and very available for anything. I'd storngly recommend him and his houseboat!
