Like many others using this hotel, I wasn't really going to care if it was going to be noisy ... but the constant noise drove me insane. Junkies, beggars and drunks were constantly yelling and shouting on the street outside 24/7, oh and throw in the church bells, street cleaners and trash collectors for good measure. With no air con you have to leave windows open and the noise was terrible. The condition of the rooms is just as others have described - run down, shabby and poorly maintained. The art rooms are quite funky, I've stayed in the Heineken room, the Chemistry room and the penis room but the novelty soon wears off. The bar/club downstairs is excellent though, staff seem reasonably OK. Security is good and it needs to be given all the low-lives that hang around the front door day/night. Another plus is the rooms being quite large by Amsterdam standards.
A good party hotel in the middle of the red light area (and on the gay mile, for those that way inclined) but if you want to get at least some sleep during your stay, consider other places.
