My first night I spent in the noisiest room ever, it was small, sticky, had a bad smell and all night long noise from the street (where there obviously was a huge party) came into my room. In addition, the serene from emergency cars and busses stopping and starting under my window completed the picture. The highlight was the drunk guy trying to get into my room at 04:00 at night. I was there for a conference so this was really unfortunate. The breakfast for 12.90€ wasn't worth it. Especially the range of fruit/ vegetables was small-not existing. Nice was the fresh orange juice. For the last three nights I could change my room which was evenly dirty and small but not as noisy. But there, small from the canalization came through the window whenever it was raining.
In the end we had to pay 460€ for four nights but the feeling was not like living in a hotel but staying in a youth camp.
