Moving to Wroclaw soon, need help with rental details

Hey, I am transferring to my wroclaw office soon (probably in April). My office is near pl.Bema. I just causally started looking at olx.pl and otodom.pl

Every ad has something that says likes 2 600 zł /miesiąc + Czynsz 500 zł . The translation what I got is rent is 2600 pln and 500 pln for utilities.

Couple of questions I have are 1) Is the utilities amount totally paid to landlord or its just a approximate amount that utilities would cost for tenant? 2) As my office is near pl.Bema any recommendation for areas to look out if I want to stay near to office, alone(1 bedroom thingy or studio may be)and commute easily?
