If you're traveling solo or sharing the room with other people not from your group, know this is a place designed to enjoy Amsterdam and its nightlife so the rooms are clean and practical, safe storage space for your belongings in the room fits a small suitcase, like the ones allowed in the cabin of the plane and a lot of entering and leaving the room by everyone is going on.
If you get a top bunk bed be prepared for not privacy since those have no curtains, also allowing for light to hit your face when other guests turn it on. Middle and bottom beds are much better in this way. I had the chance to try both.
Breakfast is definitely worth it and drinks are also very good.
In general the vibe of the place is something I enjoyed a lot, you get to meet a lot of people and have a good time right there, but I would suggest some minor improvements in customer service policies
