A group of 8 (3 girls, 5 guys) of us went to Amsterdam for 3 days in March and had the greatest time! I love this party hostel and when traveling with a large group of friends it is perfect! We stayed in an 8 person room, which was nice that there was 8 of us and we didn't stay with people we didn't know, although you can probably meet some awesome people that way and have the best time of your life!
The beds are bunk beds so they are not that comfortable but when your just looking for a place to crash after a long night of partying it works out great! The room had one shower for us to share and in a separate part with one toilet. so at least they weren't together! There was also lock boxes under the bunk beds so if you bring a lock you could put all your valuables in there. The hostel was very centrally located! It was also very reasonable priced!
The bar attached was amazing! Played the best rock n' roll music and we spent a lot of time there just drinking and the food was also really good too! The breakfast provided to us was very good and healthy, typical european breakfast spread! Which I really liked! People that weren't even staying at the hostel would come to the bar to party! it was always packed at night!
I would recommend this hostel to anyone traveling to Amsterdam with friends and looking to have a good time!
