I enjoyed my stay at Nicole's place. It's very straight forward to get to, you just have to take 2 buses from the airport. The bus station is very close to where the Airbnb is. Its in a quiet and clean neighbourhood. The room was clean and tidy, plenty of toiletries, both Nicole, hers son and 2 dogs were lovely hosts to talk to. Would highly recommend hers place to anyone wishing to stay in Berlin!
