I stayed in the houseboat with my boyfriend for 5 nights -- it was fantastic! The house is in the outskirts of Amsterdam in a quiet neighborhood surrounded by small canals, trees, hills, and gorgeous houses. Frans was an incredible host; he picked us up from the bus stop when we arrived and dropped us off at the airport at the end of our stay. He gave us a quick tour of the area, gave us fantastic recommendations for what to do, and had a cabinet of information about the houseboat and maps/guides of Amsterdam. The house itself was very well maintained, modern, and clean. During the nighttime, the bedroom can get a bit cold because it's below sea level, but the novelty of sleeping underwater and the warm blanket provided made up for that. Although the metro ride to the Central Station can feel quite long (maybe about 20-30 minutes), the distance made it feel like we were heading to our getaway home at the end of each night. :)
