Communication with Michele was great throughout the booking process and at the end of our stay. The apartment is aprox 5 minutes walk from the local metro station with cafes on the walk. The transport in Berlin is superb so we never had a problem getting back in the evening. The apartment was clean and tidy with plenty of space for the 7 of us staying there. The 3 bedrooms were a good size with the forth bed was in the living space which we knew before we went so didn't cause a problem for us.
I would highly recommend staying in this apartment and we all thoroughly enjoyed our trip to Berlin. We will be coming back in the near future.
