I have spent one week in Heike's studio, preparing for exams. It is a beautiful appartment with many elegant details, in a very nice neighbourhood, very quiet, U-Bahn, S-Bahn stations and supermarkets close by, so it's a perfect place to discover Berlin and a perfect retreat at the same time. Heike is a super nice host, always ready to help, communication was uncomplicated and reliable. I can highly recommend this place and would come back any time!
