Bert was a super host: giving us some advices for the Berlin marathon with even recovery beers, bath product to help the muscles and champagne to celebrate. Moreover, at the end of our stay, we were able to leave our luggage in the apartment for the day to be able to enjoy fully our last day in Berlin.
The appartement is really great and super clean: 2 bedrooms and a bathroom on the top floor and a nice kitchen and living room on the ground floor. The U and S nearby are really convenient.
