Lovely helpful hosts, and a clean, well equipped, and attractive apartment, also suitable for self catering any meals, though we went out to eat to make the most of the city. Really great location in the Innere Stadt, we walked everywhere we wanted to get to. Strongly recommend.
(Tip: if you want to store bags on the final day, use Wien Mitte station luggage storage, (free with city-airport train ticket) where you can also check your bag in for your flight out from the airport. Really easy and convenient, and within walking distance.)
