The hotel was great! Room is small but has everything you need, with added luxuries like a towel warmer, electric kettle, mini fridge, etc.
Best part of the whole stay was the 6th floor spa! For only €49 my girlfriend and I got to spend two hours in a spa on the sixth floor. It was private, and we had access to a hot tub, bathroom, sauna, shower, and lounge chairs. There was also a pot of tea included, along with standard mini fridge stuff (overpriced mini bottles of champagne, etc). After about a month backpacking Europe in hostels, the private room + spa was well appreciated (and fully in our budget).
