Our room was on the second floor of the back older building, which turned out to be on the ground floor (the second building is a convoluted journey up a lift, across a footbridge into a second building). Be aware there is a nightclub out back which is open till 4am Wed-Sat and you can hear the music from the room.
There was a greasy food mark on the floor of our room when we checked in which I reported to the reception and it took them two days with a reminder to get it cleaned properly.
This all being said, it's a centrally located hotel, the beds are comfortable and the blackout curtains are good (a necessity in a Finnish summer!).
