Many thanks to this very thoughtful and kind person who is Caroline. She was of great help to make this birthday's special stay happen in a very welcoming atmosphere. Despite her not being there during our stay in Berlin she had organized everything so nicely and in detail that it was as if she were there in person. Thank you for your help and for your care of the details. Caroline was a great (ghost) host and a very pleasant cheerful person. I recommend her for everyone looking for a cosy clean place in a strategic location, and looking for a super host.
