I was in Cluj last october it was definitely chilly. I actually bought a coat there. It wasn't bad though.
Cluj also has pretty insane logistics. It's a compact medieval town from the days of the austro-hungarian empire. There are three real good spots, but if you get sick of those, you're shit out of luck. Same goes for a place like Lviv Ukraine, which has a club called Metro that bumps seven nights a week, and there are a few other clubs. but that's it.
In Kiev and Prague you have nightlife options. You can be a king in Kiev due to your status. The language issue will be a problem, but if the girl likes you it won't matter.
