A nice airbnb that easily fits two, located 5 minutes walking time from Wien Mitte which has various metro lines including direct access to the airport.
The airbnb was very clean and tidy and contains all you need for a short stay in Vienna.
Ketevan was also willing to accomodate for my late night check in request and provided clear instructions that were very easy to follow.
Communication with the host was always easy and received responses within a few hours if not earlier.
