Thank you so much for the information and understanding - fantastic response!
Also, apologies for the broken english in my post. I typed it in english with a few german words and it looks like google translate automatically tried to translate to all english before submitting. For everyone's reference, my original post should have read:
Hi all,
I am looking to rent an apartment in Berlin for 2 months as I am immigrating from the UK for work.
Is it legal to obtain a wohnungsbestätigung while staying in an airbnb? If so, is it fair to ask a host to sign the wohnungsbestätigung as my landlord for the duration of my stay?
Thanks,
Joe
