This was our first Airbnb experience and it worked out very well. Jan told us which train to get from airport to nearest station and then the apartment was just 10 mins walk away. We were met by a friend of his and she made us welcome and showed us around. The flat was clean and airy and as the photos showed. She told us about the transport system. There is a tram nearby which we used most of the time getting into and around Vienna. It was a good base and we didn't spend much time in the flat. We found the bed and pillows quite hard but I think that is just personal preference. On the last day we were able to leave our bags at Jan's office nearby which was a great help as our flight wasn't until the evening.
All in all a good experience!
