Olaf is a fantastic friendly host who communicates well. His appartement is beautiful with high ceilings and 3 bedrooms. Only bummer is the noise coming from the street which is buzzing with party people on weekends, but also a chicha bar right below. No problem for young guests who want to experience Berlin night life but rather difficult for us because we came with a 6-month-old-baby. If we had known... Nevertheless it was fun!
