We've been four people visiting Berlin and living in Marek's apartment for a long weekend. The location of the apartment is great! Only ten minutes by foot to the S-Bahn Warschauer Straße and a few minutes to the nearest supermarket and Späti and Berghain. Nonetheless the bedroom and living room are quietly situated in a small inner yard. The apartment provides enough space for four people if you don't mine to sleep on a cozy couch or a comfortabe futon matress. I was surprised that the apartment was bigger than it looked in the pictures. The apartment was very clean and nicely furnished.
Marek has been very kind and well organized to make sure we had a good stay in the apartment. Check-in and check-out went smoothly. Absolutely nothing to complain about. Thank you for the great stay and take care!
