Stayed at Hannes place for a week and couldn't be happier with a place! Nicely decorated spacious apartment, equipped kitchen, comfortable bed and a balcony with a peaceful view facing trees and private park.
It's very close to city center and Wien Mitte where you can have a connection to airport and U3/U4 trains that take you almost anywhere.
Hannes is a great host and quickly responded to my messages.
Definitely will come back!
