Fantastic! So we stayed at El's place for 3 days, had driven down from Munich, reached in the afternoon and were quite tired. But the moment we entered the apartment and saw how amazing it was, all our tiredness vanished!
Clean, spacious with lots of natural light and very well done. Both the bathrooms were neat and clean. The living room with the pantry is the best part, where the window doors all open up as well.
Would definitely recommend to anyone looking to stay in Berlin and have a great time.
