Hotel is close to Hauptbahnhof (Central Station) which is why i booked there. Room was nice, only one major issue for me: the AC was not working, i changed the room but i had the same issue on the new room as well. I had to sleep with the window open, luckily it was cooler in the night, but it was also noisy, as my room was facing the Hauptbahnhof. I wouldn't go there in the summer for more than a day or two, that's for sure. ACs are ancient and probably lacking freon so all they do is ventilate the air, nothing else.
