Juul's houseboat is unique. It has an interesting history and you can even find the story of its renovation. You do have to allow for it being a houseboat though: creaking floorboards, different height flooring, some tight corners but it all adds up to a pleasurable floating experience.
There are a couple of bikes you can use, and cycling in Amsterdam is easy but local transport in the shape of trams and buses are close by too. There are some cool places to hang out locally too. I discovered Roest on my penultimate day which was excellent.
All in all. We enjoyed our week immensely.
