The Hostel of Ani&Haakien is really nice, the kitchen and the living room for all the guest are pretty and well designed, we enjoyed the stay very much. Everything is cleaned all the time and the rooms are good standaard hostelrooms with free Lockers, wich was really useful. We loved to stay at the living room with other visitors and have a beer at the evening. The breakfast was also great and delicious. I think its one of the best, friendliest, nicest place to stay in Rotterdam !
