The apartment has a good location in a quiet living area, the view from the apartment ist great. There is a good public transport connection with the U6 to the city center (approx. 10 minutes walk to the stop Afrikanische Straße), also buses run right outside the front door. The green Volkspark Rehberge and Plötzensee are nearby. At the Edeka next door you can get everything you need. More shops are available on Kurt-Schumacher-Platz.
The equipment of the apartment corresponds to the description (electrical appliances working, Wifi, kitchen equipment, bed linen and towels available), modern elevator to the 6th floor. Some of the furniture and the floor need renovation (already in progress).
Berlin is a great city, I had a good 4 months stay in Sergios apartment.
