Why is it so bad to rent there?
The reason it's so cheap there is because nobody wants to live there.
It's full of social housing tenements and crime.
There's a local football team with a large hooligan following.
As I said to Monitor, I wouldn't ask my worst enemy to live there.
Besides that there's just very little to do there, there's a main shopping street that's full of really terrible shops, with really crappy products. There's a couple of decent restaurants, but the town is usually empty by 8pm. It has a hooligan problem, graffiti everywhere, the streets aren't clean and hooded teenagers prowl the streets at night looking to pick fights. Avoid.
Bytom is literally hell on earth. I got racially abused there by some local scum and I'm Irish, so I'm more white skinned than your normal Pole. Nobody I've every met here, nobody, has a good word to say about Bytom. It's a dump, full of crimes, junkies, social housing. It's probably the worst place I've ever been to in Poland.
Bytom and Chorzow have more crime than any of the other cities in the Katowice region.
Y'know man, if you wanna save money and live in a sh!thole, then it's your choice, but you get what you pay for. The cheaper something is the crappier the area you're going to be living in.
Plus travelling from Chorzow to that university will take roughly 50-60minutes, more during peak times.
From Bytom it would take even longer, about 20-30 minutes longer.
If I was you, I'd be looking for something in this area: goo.gl/maps/4SWrZ
Close to your school and walking distance to the city centre.
Up to you, but no way in Hell would I touch Bytom or Chorzow.
