Jonny's place was just about perfect for us. Both bedrooms had balconies, and the beds were very comfortable. The main bathroom has heated floors, which was very nice in December! The kitchen was fantastic, with just about everything you'd want.
The location is great, being just two blocks away from Wien Mitte station, which has a non-stop train to/from the airport. Upon departure, it actually acts as an extension of the airport, with the ability to check your bags right there!
Jonny was always responsive, not to mention both pleasant and understanding.
Highly recommend this apartment!
