Close to Statdmitte/Spittelmarkt. My apt has the best location you could ever wish for. Close to all the tourist attractions and night scene, AND nice restaurants and bars.
Located in a high building, which is very unusual for Berlin, you can enjoy the most amazing view of Berlin while you're enjoying your wine or coffee.
Nice modern building with concierge and elevator, my apartment has a fully equipped beautiful kitchen connected to the living room.
