The room has no AC in the summer time, has to keep the window open to have the air flow, however the room is at the first floor right toward a plaza while the fountain dripping and drunkers shooting that making lot of noises till 05:00 am. We stayed one night without any sleep. Called to the front desk, got the answer that few AC room were occupied, also the whole hotel didn't have any ventilator. This is unacceptable for a room price for 100 euro. Very dispointed and would never go back again!!! Our next day trip is ruined by completely sleepless whole night in Aachen.
