This is a very nice flat in an excellent location just moments away from Potsdamer Platz and within easy reach of the historic Mitte quarter. Very good transport links. Martin was a perfect host : his responses were quick, he met us at the flat, gave us lots of tips and advice and recommended two good places to eat nearby. The flat is spacious and clean, with direct access to a small courtyard, and the beds comfortable. Well equipped for short stays. Only thing missing for a longer stay is a washing machine / dryer.
