I stayed in Mario's apartment for five weeks and it was an absolute pleasure. Working in Berlin, it provided me with a comfortable home environment when I needed it. I enjoyed the view at the front onto the wide Allee and the quiet, sunny aspect of the bedroom at the back of the building was most welcome, especially when there was sunshine amongst the grey Autumn days. The location is perfect - with various modes of transport at the doorstep access to many parts of Berlin is easy. The neighbourhood is interesting and has everything I needed in relation to food, shopping and entertainment. Correspondence with Mario and Carmen was very efficient and hospitable. I would definitely stay here again when in Berlin.
