Michael was very responsive to our messages, he was waiting for us at the apartment when we got there which was way before the check in time but as the apartment was ready he let us in straight away. The apartment is big & airy & just as described in the advert, everything we needed was there including adaptor plugs which we had forgotten. The location is brilliant, supermarket facing, tram stop 2 mins away & cafes & bars one block away. Michael was also very kind and ordered us a taxi to the airport when we were going home. I would highly recommend this apartment If going to Berlin, really can't think of any negatives
