Amadi Park Hotel is clean, friendly and inexpensive. I paid 65 euro's for a single room, wich had all I needed -and nothing more. The minibar is free, but there was just a can of coke in it, so that's nothing to get to exited about. But the gesture is very nice, as is the gesture of free -and very good- coffee.
The entrance is hard to find as it is located in a big apartment building. In the Amsterdam context (horrible but expensive hotels) the Amadi is absolutely fantastic.
