Katharina her apartment is an absolute recommendation. Its location is perfect if you are looking for a calm, safe and friendly neighbourhood in Berlin. Also, it is very well connected to the touristic centre, if you are looking for healthy bars, not too touristy restaurants and some great shops, we definitely recommend to stay here. If you are looking to visit some of Berlin's finest clubs and East Berlin, its only a €10/€15 taxi drive away! This combination with amazing beds, super comfortable linnen and a amazingly hospital host creates the perfect apartment. We will definitely be back :)
