INTENSE ODOR OF HUMIDITY.
My son and I are on a long trip through Europe and to make our money go further, we usually look for a cheap and simple room to stay. That is why we rented this room.
We got the simple room, but the big problem was that it came with an INTENSE odor of humidity. It made me sneeze and cough all night.
We stayed the three nights, but we stayed out of the room all day and only spent some hours sleeping in there.
