My family is about to cross the border with Poland (that's mom​,​ 2 kids - my sister and brother​,​ and my sister-in-law)​,​ they're from Ukraine (from Poltavska obl) and looking for a place to stay for some time. I will be really really grateful if anyone can help with this. We can pay for a living as well​,​ not a question. But​,​ please​,​ anybody who lives in Lodz​,​ Poznan​,​ Krakow area — let me know​,​ as soon as it possible​,​ please
