I highly recommend Michele's place to any one looking for Airbnb in Berlin. Everything is on ground floor, no stairs to climb. It's clean, cozy and functional. We do not have to go far to get a meal, everything is walking distance from his place.
We arrived 3 hours early before check in, I called Michele and he accommodated us. He let us check in early even when the place is still being cleaned.
The service is outstanding.
