A really awesome hotel. It's cheap yet huge and very easy to find. Situated at the town centre close to restaurants and pubs, it is close to almost everything you will need in Amsterdam. They even got signs on lampposts leading you to the hostel and this really impresses me. The breakfast is also very nice with ham, cheese, bread... Staff there are knowledgable about various attractions of Amsterdam and the quickest way in getting there!
The staff there is very warm and welcoming. It is also close to the beach and a simple and short walk from the hostel will take you to the central station of Nice. It shouldn't be a trouble looking for the hostel.
The staff and the location is very nice indeed. Right by the port and close to the Notre Dame, you could go to a lot of places easily from there. Only areas for improvement would probably be the facilities, only one room for shower and one toilet, the breakfast is also a little too simple, though its free. Anyway, it has a big kitchen so you can cook.
