Vi stayed in DoubleTree Hilton Kosice 3 nights, room we got was meant for two, but with no space for luggage, so at some point I had to jump over my suitcase when going to sleep... Room was very clean and aircondition worked well (was above 30dg outside those days)
We had a lunch in restaurant - basic salad and sandwich... it took then more than an hour (Saturday afternoon) and after speaking to the waiter, 15 min afterward we got it... however, despite of fantastic taste of my salad, I found a black hair (!) and had to return it... Waiter commented it that the chef forgot to take gloves (!) when making it...
Else hotel is very central, easy to reach any place in the centre, we also ordered breakfast to go -it was a very good, rich package of everything - baguette, fruit, water, etc...
