Axel is very kind, welcoming and responsive. His place is extremely clean, ordered and has the good amenities. It is very well located, just 5 min away from Checkpoint Charlie by foot, 10 min walking distance from Potsdamer Platz and 20 min to the Brandenburg doors. There is a supermarket and pharmacy 2 min away and lots of restaurants and shops. Moreover, it is centrally located in Berlin Mitte and just 5 min walking distance to one well connected metro station. I would definitely recommend his place.
