We celebrated my wife birthday in Berlin last week and had a great time in Kelly's apartment. It was clean and feels like our actual home with well equiped kitchen. The room is big with large windows. The apartment is in very nice residential area and quiet. Everything we needed was nearby, good transportation, the U-bahn on one side and the TXL bus on the other side which goes to Tegel airport and to the train station. The 'Arminius Halle' which is a great place to eat is just 2 minutes walk. Kelly was very friendly and helpful with any question we had.
