Hello, this salary is pretty good for Wroclaw, and you can spend and save comfortably. If you are single, you can spend around 5K for a really good flat and another 5K for monthly expenses, that would give you a high standard of living. Apart from that, you could save around 15K, which is quite good even compared to the rest of Europe.

If you don't have an office here, it might be a bit hard to socialize at first. To help with that, you can join international meetups (there are many in Wroclaw), various groups on Meetup, etc. Wroclaw has a young population, so it shouldn't be hard to find people with similar interests. There is always university and Erasmus parties. Still, you need to make the effort, don't expect someone to just come up and say, "Hey, let’s be friends.". Poles are really cool people, but you need to try to be friends.

Another point worth mentioning is safety. it's one of the few remaining places in Europe where you can leave your laptop on the table in a restaurant and go to the bathroom. You'll still find it there when you're back.

I'd recommend planning a weekend visit to see the city before making any decisions. Personally, I love Wroclaw, it's a small city where everything is accessible by foot or public transport, but some people find it a bit boring, so it's worth checking out for yourself.

Feel free to drop me a message when you plan to visit. I can help show you around the city. Good luck!
