Stay here! Nora is gracious and made sure that check-in was a breeze; she even went out of her way to help make sure I could see a concert. I really enjoyed the apartment's location - it's close to the main train station and the Belvedere, 15 or so minutes' walk from the Ringstrasse. The room had a cultured (books and CDs) feel, well decorated, and a "crow's nest" vibe from being on an upper floor of a beautiful old apartment building (her floor is newer construction, but the ground floor's very atmospheric entry hall was a nice perk). It was warm during my stay, but with the fan on or with windows open at night it cooled down just fine. Very good home base for a stay in Vienna.
