Although I didn't met Frans face to face, he was always available for me. Was very welcoming, and even let me stay a few more hours for a late check out. Next time I'm in Berlin I'll know where I'm gonna stay. The appartment was wonderfull. Clean and rennovated, very luxorious!!! Quiet at night with great location: bars, cafes & restaurants around the corner, and only 5 min. Walk to Ostkruez S-bahn station.
