Help Valentina and her family start over

Valentina and her husband came to Portugal to work, leaving their 2 teenage children with Valentina’s sister in Ukraine. When the war started, the sister managed to flee to Poland with the children where they were reunited with their mother. Now they have safely arrived in Portugal and want to build a new life here together. They found an apartment where the landlord is willing to forego the usual IRS and guarantor requirements, but asks for one month rent as a security deposit and 2 months of rent in advance. They have raised the deposit and are now seeking assistance to cover one more advance payment to move into a safe and comfortable home where they can build a new life here in Portugal with their kids. Their current landlady is threatening to throw them out this weekend, at the moment their only other alternative at the moment would be one of the refugee shelters. Any donation, no matter how small, is immensely appreciated Thank you!
