I booked a suite, but unfortunately it was already given to somebody else, by mistake of some former employee. The staff was nice and kind, trying to solve the problem in other way, so we got a bigger room (not a suite, but still much bigger than the classic ones) next day.
Apart that,the hotel is nice, everything was ok. Not in the very center but very close, the last 200 mt are quite steep , it wasn't a problem for us but for somebody else it could be .
In the night there are some "workers" in the main street , but we often preferred the little quite and nice street aside (very quiet, there is a cemetery there :)) going straight to/from the center.
Never felt in danger anyhow, Cluj seems to be a pretty safe city. We liked, both the city/region and the hotel
