This could be one of the best trips I have had in Europe. The house is pretty and tidy,everything is perfect,you can do laundry and cooking. The subway station, bus station, and tram station are all quite near. Besides, down to the flat, it is the famous Berlin Wall museum. Really worthy visiting. It’s a hundred percent safe place for anyone who wants to travel alone. Thanks Berlin,thank you Anke, thanks for providing such a warm and safe for us travelers.
