Everything is ok until I meet the manager. The first day the receptionist kindly offered me an upgrading, to a four bed bedroom. However the next day when the manager came,he refused me with a quite rude actitud. Without any explanation, he told me go back to my room, they don't have any other room for me. I understand sometimes a room can be empty but be sold out few hours later. But if you promised me an upgrading but finally you can't, you should kindly told me and apologize for it.That is what we called a service. I felt like I lived en a prison rather than a hostel , and was facing a warden. However, the recepcionista is very kind and considerate. He apologized for all the thing.
