Would highly recommend staying in Duc Son's place in Berlin. The apartment is well situated in the Prenzlauer Berg neighborhood - close to restaurants, shops, grocery, and the M10 tram stops right at the corner. The apartment was very clean and had all the amenities we needed for our family of four. We loved the back balcony overlooking the courtyard and the sunset. There were bikes available to rent and Duc Son was super accommodating and communicative to us throughout our visit.
