We're looking for a small flat in Hamburg, please help!

Dear Friends! I need you help so much! My sister is looking for a small flat (about 40m2) in the centre of Hamburg.

If you have any informations or your own flat to rent please contact me(joanna.gwis@gmail.com). I will be very grateful. It's very important because she will start her new work on Monday and can't find anything reliable and safe only suspicious offers. Please help.

Thank you so much!
