A worthy room in Berlin! I appreciated everything: Maria-Antonia is a kind, proactive and friendly host; the flat is nice, well equipped and comfortable; the location is perfect: 15 minutes by walk from Alexanderplatz, and just a few meters far from the closer metro station.
I also liked the building, an historical architecture of the communist Germany. Karl Marx Alee is a must see in Berlin :-)
I definitely recommend Maria-Antonia's room
