The boat is excelently located, just 5 min walking from Amsterdam Centraal station, which is the heart and common joint of almost every line of trams, bums, metro and traing throughout Amsterdam. Anyway, you really don't need much the transport, bicycling or walking are always best options.
Also, there are at least 5 rent-a-bike places very close (Star Bike being the cheaper option)
The atmosphere is very nice, and the owner treated us really well. The boat is *extremely* clean and well maintained. Some people may fear wether the boats waves with the water: it does not, because that part of the water is more kinda river water. You won't know you are in a boat.
The rooms are quite small, but hey, it's a boat!
The breakfast is just OK.
I won't recommend this place to my parents (they would need more space, and being in good shape to go down those stairs...), but I would recommend it to anybody else, HANDS DOWN!
It's a really good option for young people in general.
