Excellent base for exploring Berlin.
We spent 6 nights at Marleen's place in early August 2017. We enjoyed the spaciousness and high ceilings and above all the location. Our kids appreciated the wifi. The flat was peaceful and clearly the building works mentioned in 2016 reviews are now complete. The balcony overlooks the restaurants in one of Moabit's main streets, which is busy, and interesting, the flat is 1 minute from Birkenstrasse's U-bahn station and there is a Edeka 5 mins away. We dined out at local restaurants 2 of our nights there. You can be on the Kurfurstendamm within 10 minutes and in the middle in under 30 mins. The flat is a little rough around the edges but in keeping with the general Moabit milieu and there are occasional smells from the restaurant next door in the stairwell but not in the flat. Thoroughly recommend - we would stay again.
