If I had to condense my experience at Martin's place in a word, it would be: SILENCE. I really enjoyed the quiet and peace of his little apartment. Easy to reach from Schonefeld, and if you like to walk, a lot of nice little places where to grab a bite. (by the way, Martin: thanks for the berlinburger tip, food was amazing!)
The apartment is perfect for a couple on vacation or for a single traveler as I was on this visit. Bed is very comfy!
