Hanna's apartment is fantastic! Nice and cozy, we could tell Hanna had gone to great lengths to make our stay comfortable and make sure we had everything we needed. She was always contactable and was even nice enough to let us do a load of laundry in her own apartment. Really easy walk several ways to centre of Vienna, and Hanna had some great recommendations for things to do - make sure you ask her about the standing opera tickets! Highly recommended!
