Difficult to enter, nobody in the reception, and the button sent by email didn't work, I had to call for them to remotely open me the door (entrance and room ones)
Very noisy from the cars passing next to it, since it is in the ground level.
A little claustrofobic, since there are 2 doors (beyond the entrance door) before getting in to the room door.
The paper left in the room with instructions and information was in german language, no english available. They knew I was a foreigner who had commuincated previously in english language.
As positive aspects, there is a fridge with water where we can put other products, the WC is not bad and the room is well heated.
