The location of the hotel is nice at the end of a side street, off the main streets. The first impression is lovely. I was greeted by a receptionist who was, for some reason, very unfriendly, and seemed to have been forced to service the clients, i.e., me. It was explained to me that I have chosen a Superior room so it is a non-smoking room. I looked at the room and saw nothing Superior in it, including very unpleasing permanent carpet stains, and a very limited space for seating next to the desk. As I am a business traveller, the desk is important to me not less than the bed, so I asked to see the regular smoking room. The lady sent me to see the other room with no instructions of how to get there so I had to stroll around and get back to her and "force" her to explain to me how to get there (the property is divided into 2 units with plenty of stairs and corridors). Shockingly, it was indeed smaller so I gave up the smoking option and chose to stay with my "Superior" rooms. Other than the carpet and the narrow seating, the room was fine. Luckily, the weather was nice so the lack of A/C did not trouble me. There was a minibar in the room, which was positively surprising. The morning check out receptionist looked much friendlier than the check in lady. Maybe she had a bad day, but a feeling cannot be easily changed. All in all, I would probably choose another hotel for my next trip to Hannover.
