We stayed three nights in Martin's apartment. We were all wowed by the cosy and clean apartment the minute we stepped inside. A big studio apartment with ample space for four of us. This apartment is not his home but a service apartment. We were provided everything we needed for the stay.
The train station on U2 line was just 2 mins walk from the apartment. One stop to Potsdamer Platz. The apartment is very convenient and safe to walk at night. Martin gave us instruction on how to get to the airport from his apartment. It was easy and convenient. U2 line to Ernst ReuterPlatz, then bus X9 to the airport.
Will visit and stay in Martin's place when we are in Berlin again.
Thanks Martin. Merry Christmas and a Happy New Year 2017.
