I have traveled to over 60 countries and frequently stay in hotels and hostels, and I have to say that this was my absolute worst experience that I can remember. The hostel itself is dark and cramped. The maze of dark hallways is a dangerous fire hazard and I am surprised that it passes code. I had a very negative experience with the management double charging me, as well. They changed their justification/story a few times, but the one that they settled on was not plausible, and even if true, was not a proper justification to keep my money. It was the kind of customer service experience that sadly is somewhat common in the Netherlands; way more focus on trying to prove they are "right" than putting the customer first. They also have a mold or fungus problem in their shower as I developed some kind of minor rash. I normally love a good hostel; I stayed at King Kool one night of my visit and they were amazing: better location, courteous staff and location, way more spacious, and better amenities. In short, do not stay here, stay at King Kool.
