Life / Cost of Living in Lodz [50]

Hi!

I got a job offer in £ódź and I'm trying to figure out how to negotiate my salary based on what I'd need to live in the region. I have friends in Poland, but they live in Wrocław and Krakow and work in completely different fields, so I thought I should get more specific details.

I've never even owned a credit card because I was raised to be averse to debt so I'm not a big spender and I won't have to pay rent. I'll share a two-bedroom apartment and all the expenses and I will not need a car. I cook my own food even to bring to work with me because I have to stick to a hypoglycemic diet. I don't drink, don't smoke and don't go out much. My only vice is travel and the only major expense I expect is weekend trips to see my friends and a bit of exploring the parts of Poland I haven't seen before, but since I'm generally staying at friends, those don't cost that much either.

I'm not on any medication, but I have to stick to veggies and lean meat so on a slightly off topic note, are there a lot of farmers' markets where I could get fresh vegetables to avoid Tesco tomatoes and the like? I'm only asking because where I live it's not a general rule that every town will have a good offer, depends on the region.

How much (per month) would I need to live in £ódź then?

Thanks!
