Peter welcomed us very early and we could leave the suitcases at the apartment, which it was very helpful to start our sightseeing. He gave us some advices from the city. The apartment was perfect. We definitely repeat whenever we are going back to that beautiful city. There is a city bike station very close to the apartment, which is a great mean of transport to visit Vienna! Thanks also to Katherina, she was so helpful also!! Best regards, Hugo.
