Stéphanie's apartment is perfectly organized, quiet and confortable. I spent three days in Belin with my son and we had a great time. The apartment is well located, close to the Alexander Platz and just 20 meters far from the metro station. We were able to walk to the museums island in 20 minutes.
It is a great place to stay in Berlin ans Stéphanie was very helpful to facilitate the check-in and out.
