We just stayed one night on the house boat. It was really neat being on the water and the location was unbeatable. The lock was a little confusing and hard to open but after a couple of times we knew how to push and pull. It was quite cold in the house and we couldn’t increase it. But I think it’s just the nature of a houseboat, so not anything you can do. Shower is difficult to get in and out of, my older mother struggled, but the water was hot it has all the amenities a bathroom needs. Overall we loved the location, but for comfort reasons we might chose a hotel next time. But staying on a house boat in Amsterdam is kind of a once in a lifetime experience. The hosts were extremely responsive as well and let us drop our stuff off early which was a huge help.
