The hostel is located at a very convenient location i.e. right outside Blaak Station which is 5 mins on metro from Rotterdam Central. The hostel is built in the Cube Houses so one would be staying inside a tourist attraction and yet its a silent location. The people are welcoming and greet you with a smile. The rooms and infrastructure is brilliant. However, the lockers are located next to the reception and not in the rooms. The hostel has a convenient bar and nice common area.
Overall a very good experience!

Considering the price (EUR 29,50 pp) this accomodation is very good! It is clean and centrally located! Not a lot of choice at breakfast, but what they have is good. Would stay here again!

Looks really cool from the outside but not worth staying in - I think there is a show house there so visit that instead of paying the money to stay here.
The staff were a mix of some nice and some grumpy making you feel like you'd put them out when asking for help.
The room was really clean however it was really bland and boring. The rooms and the hotel have no character once you're inside. There was nothing in the bedding area of the room expect the bunks. The matresses have water protective covers which got quite hot but at least you know they are clean. The sinks aren't in the bathroom but rather in the hallway of the room. The shower has no where to hang clothes up once your in there and as its like a small wet room there is no where to hide them so they don't get wet. It was ok for us as we were friends and didn't mind walking about wrapped in towels but travelling alone and sharing a room it would be difficult to shower and change in private.
The location was good, right next to a train station. There is also a really good pub close by with friendly staff and customers, 1 euro beers and they 'allow' smoking inside! With the train station behind you walk under the hostel and directly round to the right so you end up by a mini mariner, I think it was an Irish pub.
Best = Cleanliness
Worst = Inpractical rooms and boring.

this is the best hostel, though also the priciest that i have been in. paid 30 euros for a night's stay in a 4-bed single sex dorm. includes breakfast and fresh bedsheets that you put on yourself.

the setup is cool that you have shower, toilet and sink in separate areas, so you can get lots of people through the morning and shower routines. breakfast is adequate, with lots of bread, cold meats. juice and coffee comes out of a machine, which isn't very tasty. but there is fresh fruit.

beds were comfortable and great location as it is central, next to a big station - Blaak, so trams and metro are there, you can even take an inter-city train from central station if you wish.

checkin was quick and clear, no secure room for left luggage but its all next to the reception counter. it has a bar, but i thought the independant one below the hostel was nicer.

very clean and fresh colours, they offer discounted tickets to museums but were out of them when i was there. roughly 15% off the normal price.

only bug bear is no shampoo or soap for showers, so bring your own! towels can be rented for 1 euro, but its rather small, like the size of a hand towel.
