The appartment is so central we just needed the public transport to go to Belvedere Palace and Schonbrunn Palace. We arrived by bus and the bus stop is round the corner so we didn't have to hurry to get on time to the airport.
Sil is fantastic, she responds the messages so quickly and she is also kind as we had a problem with the coffee machine and we had a new one in half an hour. She was in front of the building at the time she told she would be there. She explained us everything perfectly.
