I loved being in this self-contained appartment which is perfect for one person. In general it had everything I needed for a month-long stay on my own. It was clean and tidy. Rather than using the narrow desk beside the bed in the living-room space, I moved my laptop workspace into the kitchen. This was possible as the kitchen table is expandable so I could eat from one end and leave my computer set up at the other. I found the bed comfortable. Wifi, TV and tech stuff all really good and there is also a wide selection of books including some in English which I took advantage of.
Brilliant location in Pankow with several choices of direct transport links to various parts of Berlin. Lots of places to eat in the locality and Alphi's organic ice-cream shop on the corner was a bonus in these over-hot weeks in the summer. The apartment is behind the street-side apartment block, so it is quiet and away from direct sunlight for most of the day. This meant it was a lot cooler than it might have been when outside was above 30 degrees.
Christina, who handled all communications, was attentive, helpful and gave wonderfully precise instructions how to get to the apartment from the airport on my day of arrival.
All in all, if I return to Berlin for an extended stay I would very happily stay here again!
