Heike was very warm and welcoming, and responded very quickly to any queries or issues that arose. The flat is in a fantastic location overlooking the beautiful little Lietzensee Lake, which provided a nice place to walk and have picnics. Everything you need is in the neighborhood, along with great transport links to the rest of Berlin. An issue for me, however, is that the building is next to a very busy four-lane road. The flat was quiet if the windows could be closed, but we were blessed with very warm, sunny weather during my stay. It would also have been very helpful to have a flat 'guide book' that listed instructions for operating things, things in the immediate neighborhood, doctor, dentist, etc. But if you do not mind steet noise, it is a good place for a shorter stay.
