I really enjoyed my stay in Marie-Therese's spacious and light flat. Great location, particularly for those who like to walk to town. A detail that hasn't been mentioned yet: It's the perfect place to be for those who have special dietary requirements (it's very close to the Allergiker-Cafe and Cafe Phil (wonderful gluten-free breakfast) and not too far away from "Zum Wohl" (gf restaurant). The check in and the storage room for luggage are very handy (self-checkin).
A piece pf practical advice: If you stay there in summer I would recommend to bring a pair of ear plugs as the Wiedner Hauptstraße can be noisy at the weekend. Nevertheless I would certainly book the accommodation again.
