Hello,
ask Caritasverband Frankfurt for help: ****://bit.ly/2acp9oR (Site's language is in German).
(see Contact persons on the right side of their homepage, keyword "Kontakt).
Ask project team 'Shelter Frankfurt'
They give only few informations in English: ****://bit.ly/2acu9tB
But they are on (German) facebook: ****://bit.ly/2actMPF
Mail contact: project.shelter-ffm@riseup.net
Kind regards, Jan
