Study / A Portuguese student wants to study in Poland [10]

hello
I am a Portuguese student who will graduate within 1 semester.
I was thinking of doing masters degree abroad especially in Poland (a friend of mine who was in erasmus convinced me). I researched about Wroclaw and I was very interested.

I have been a few days researching the cost of living, but nothing like talking to Polish guys. In recent years the cost of living has gone up? In research I saw that I can rent a room to pay 250pln. Is it realistic? and food? Roughly, how much spend on average a student in Wroclaw?

I have many questions, because I intend to live in Wroclaw in the next two years. and basically I'm not rich, so I have to search very well.

Since I am still doing research, anyone has advice or suggestions? would be a great help!

Thank you very much!
if there is someone thinking about traveling to Lisbon I can help

Sorry my english (one of the reasons for wanting to study abroad)
