We were quite disappointed of the Hostel Altido. We had a room at the first floor on the direction to the street and it was so loud, we couldn’t unterstand a word in the room nor sleep because of the noise from the street. Because the room had no possibility for air circulation we had to leave the window open, otherwise it would have been incredible hot in the room, even though it was just 20 Degrees outside. When we ask for a room switch, they told us, that there weren’t any room, even though we checked online for availability and there was! Besides the mattress was so small you could hardly sleep on it when you are two persons. We can’t recommend that place to anyone who gets a room up front or isn’t a single sleeper.
