The place is in fact better than it looks on the photos. The flat is very comfortable and has everything you may need for a short stay. The location is superb, just in front of Görlitzer Park, 2 minutes walk to the nearest station (U Schlesisches Tor), and surrounded with lots of bars and restaurants.
Sarah is a very friendly and helpful host, communication was super quick and easy. She kindly allowed me to make a late check-out.
Many thanks and happy to come back again.
