We had a wonderful stay at this really cool flat in Kreuzkolln during our four days in Berlin. Betty and her family are incredibly friendly, kind hosts who gave us lots of suggestions for things to see and do (and eat!) in the neighborhood. The apartment itself is very cozy with cool art and warm lighting. As others have noted, you share a kitchen with the coffee shop, but everyone is very accommodating and it wasn't an issue. You're super close to the U-Bahn train that will take you everywhere in the city, and the nearby restaurants, shops, and canal make the neighborhood a great place to spend time. Would highly recommend this place, especially if you want to stay in an interesting neighborhood in a quirky and cool space.
