I stayed in this flat for a few days with 4 other friends. It was clean and just as beautiful and cosy..just as it it appeared in all the photos. (Maybe even bigger in real) The neighbourhood was lovely and very safe. It was very easily accessible from the airport, was just a 10 minute walk away from everything you could ever need. Accessing all other parts of Berlin was so easy.. by foot and by train. I highly recommend staying here regardless if it is a short or long stay. The only issue was that there was a bit of a misunderstanding with the check in. May be worth calling both Carmen and Daniele when on route.
