We came here for a weekend trip and stayed for two nights at Amsterdam Hotelboat. It's in the vicinity of Centraal, but if you want to go to the city, you'll need a cab. The personnel is basically non-existent, noone helps you with anything. And if you happen to talk to the Hotelboat guy, he'll only bend your ears with redundant crap about the hostel business, so just don't. Rooms are almost clean, toilets not so much. If you go there for the cheap price that's ok, but you gotta expect cheap conduct, cheap quality and cheap people, too.
