We had the best time at Engelbecken, the location is perfect, you´re in the middle of Kreuzberg, but still at a cozy corner. There´s immediate connections to sightseeings, but also the original little restaurants and spätis. For kids it´s spectacular as you have your own entrance to a little pet zoo (in the middle of Kreuzberg!!) and some great options for nightlife. Falko was always available for any questions and super helpful - I really hope I can return there soon!
