I'm not getting any accommodation in poland. Head is on fire :(.
Feck there is loads of accommidation in szczecin, and very cheap at that....
The thing is you already know how much you will be earning, so I can only presume that you are working for a company either based in szczecin or has very big dealings there !!
If this is the case then surely they will be able to provide you with all the information you need about living there ??
