I think I’m getting scammed

Im from India looking for an apartment in Munich and soon came across this listing on Facebook. Its a 61 square meter apartment for €550. Unbelievable right? So I email the landlord and she’s a doctor at Köln. She asked me to pay €1100 to book the place. I asked for some proof because a friend of mine got scammed the same way. Now she sends me her ID and stromrechnung  as proof. What should i do ? I am in desperate need of a place but don’t wish to trust someone with just an ID.
