We had a great & comfortable stay at Ari's cozy apartment. Ari had given us very clear directions of how to collect the keys and from where. It was very convenient. But as we had given very specific time of arrival, we happened to meet Ari as we reached. He guided us through the apartment. Those days were hot days in Vienna and Ari had provided 2 fans and 2 humidifiers for us. The apartment was clean and the location was perfect. Ari even helped us by calling a cab for us when we needed it. Ari's response time was very fast through the airbnb connection.
