We went to Amsterdam for an extended weekend and enjoyed the stay at the house boat a lot! It was super cosy and we instantly felt home. With the bicycles it doesn't take much longer than 10-20 minutes to get to the city center, depending on how fast you drive and where you go, but it's super easy to get around. Juul gave us awesome tips about where to eat and how to get to places. And when we had a problem with one of the bikes he fixed it right away.
Very helpfull and nice host, who quickly answered our questions. I would totally book it again the next time I come to Amsterdam.
