Life / Flat Rental Price - Do you think its really expensive? [13]

Hello dear forum. I am seeking a opinion regarding my situation. Im currently living in Rzeszów for some months, and I always felt that what im paying for my flat, is a bit expensive. Now, I dont know if my land lord is ripping me off, because im a foreigner, but 2 or 3 opinions I asked to locals, they told me my rent was a bit expensive. I want to say, im living in a "flat", well, it seems more like a garage annex, for one person, very very small. It was a small bathroom, a really small kitchen, (not like kitchen) its more like a really small place to cook, next to my entrance door, and one room. This flat or studio is very small, I have the fridge in my room because there is no other space to put it. Normally my landlord asked me around 1030 / 1050 zlotys for the rental ( the bills for water, gas etc, are included here) but this month, he asked me for 1128 zlotys. Im barely at home, since im working all the time. and I dont use so much water etc. I have to pay also for internet (cable, not wifi). Considering these information, Do you think its really expensive? Because I was thinking about searching for something more cheap or a room.

PS: Also, i remember when we made deal, he asked me if I could sign the contract, which said I was only paying around 800 zlotys if im not mistaken, but in really im paying 1000 or more. Thank you.
