Prenzlauerberg and specifically, Justus' place, is the place to stay when visiting Berlin. He is a great communicator. His son met us at the apartment, which is soooo spacious, to check us in as we arrived from the airport. We visited in November but his house was warm and comfy. It is well connected to Berlin's wonderful, extensive and easy to use transportation system. Laundry, kitchen, location - what else to you need when visiting a major city. He even provides an underground parking spot if you bring a car. Stop looking for other places to rent. This is the one!
