Sleeping in opened corridors, you sleep in a tent which you can't close. Anyone can get into your tent. The tents are separated by a relatively thin material. A couple that was evidently having a good time having sex, hit me through the "wall" of the tent while I was lying in my bed (a truly traumatizing experience). The bathrooms were disgusting. The toilets were smelly and there was pee on the floor. The showers were not much better. One of the showers I wanted to use smelled like pee and in all of the shower cabins, there were long hairs lying on the floor and many of them were attached to the cabins' walls. I did not feel safe in the "room"/tent/corridor where I was supposed to sleep with 3 men so I changed to a "private room" which appeared to be an opened tent as well. I hated every second of the experience and I will never choose to sleep in a collective ever again.
