The location and view are stellar and the experience of staying on a houseboat in Amsterdam was so cool. The boat is split into 2 apartments, and we didn't have a very good experience with the longterm renter on the other end of the boat. He played loud music late into our first night, and then again on our second night from about 3 AM to 5 AM. I texted the host after the second night and she said she would get him to stop, which worked. Maybe that was really unusual, because I don't see many other people here complaining about it. But the renter on the other end of the boat was also unfriendly, had a lot of people coming and going, and put off a kind of aggressive vibe. Not sure it would be a great feeling for certain people or people traveling alone.
Other than that, the place was great. There are some quirks, like the water temperature in the shower changed a lot, a cabinet door isn't attached, an opening to the boat had no way to latch it (it would be difficult but not impossible for a person to fit through there), and all the bedding is single sized, despite the fact that the beds are queens. But none of that bothered us much. And compared to many European hotels, the boat is actually fairly spacious. Sitting on top of the boat (there's an outside option and an inside option) and watching other boats go by provided hours of entertainment. It's a particularly beautiful spot for a sunset view.
