Our stay at Stefan's place was terrific. Our three most important criteria for rating an Airbnb rental are convenient location, cleanliness and a comfortable bed. We also value a quiet neighborhood at night and a host that responds quickly to our emails. Stefan's place rates as A+ in our opinion. The UBahn was a short walk from the apartment and we felt the neighborhood was very safe at night. There were lots of great restaurants minutes from the apartment. The park right next to the apartment building was very nice and we saw people with children and dogs every day. The apartment was spotlessly clean and we found the bed to be very comfortable with nice, fresh linens. We slept soundly as it was a quiet neighborhood and we were never disturbed by noise from other tenants in the building. Stefan was quick to answer emails and very accommodating when our flight to Berlin had to be rescheduled at the last minute. We would definitely recommend this Airbnb rental to others. You will find this to be a great place to stay and Berlin a wonderful city to visit.
