Martin was very quick to communicate with us and answered all our questions. He made arrangements for our arrival and departure that made our visit very easy. The apartment was even better than the pictures and description and was very clean. The kitchen was well equipped with everything I needed to cook for our family. The balcony is a great plus for the apartment. The apartment was perfectly located for our visit with family a block away. There are restaurants and groceries nearby. We hope to stay at Martin's apartment in our next visit to Berlin.
