We came at night so Simon and Ben arranged a key safe for us to do the self check in. It was easy and then Simon still met us the next mornings for the personal check in!
The Airbnb is just like the pictures. Bigger then I thought! Especially the bathroom. Kids could run around safely as the place has an big open room for the living room, dining room and the kitchen. Within 3 minutes we could get a bus or a train which took us directly to the city, airport and central station.
The hosts are super nice that they made sure everyday we got a good day. I can only recommend this place when you go to Berlin with a big pack of family or friends!
