The apartment was lovely, it had a little balcony to enjoy some sunshine and the bed was comfortable. Bernd and Katja were great hosts.
For noting: the apartment is on the 3rd floor without elevator (as mentioned in the listing) and the fridge is a half size (bar fridge) but the supermarket is close by for you to restock as needed.
Prenzlauer Berg is a great area to stay, with lots of little bars and restaurants close by and easy access to S-Bahn, U-Bahn, bus and tram. We enjoyed staying here amongst the locals.
