All I can say is WOW! This is the best AirBNB our family has ever stayed at. Bernd's apartment is top of the line not to mention Bernd who is indeed a Superhost\legend. We had a family situation come up while at his place and he was more than helpful with his assistance.
I will be highly recommending this apartment to all my family members and friends. Everything in the apartment was top notch from the welcoming pre-stocked fridge, the large balcony and all the appliances in the home from the Sonos system, Nespresso coffee machine and electronic windows shades. If your family is traveling to Berlin, this is the place to stay. Also, right beside the S and U train lines.
