I stayed in three different dorms in Amsterdam and this was by far the best one. Clean. You have your own plug and light by your bed and a security box. There aren't lockers big enough to fit your entire bag but there are lockers big enough to fit the important stuff.
This place should be classified a frat house not a hotel. The mattress was stained with god knows what and the towel they give you should be called a washcloth not a towel. It is nicknamed the worse hotel in the World and it is.
This place is nothing special but had clean sheets and a clean bathroom.
Phillip was an excellent host and gave a great introduction to the city, which was much appreciated as I was traveling alone and unfamiliar with the city and transport.
