A little out of the main touristy part of town but super close to a metro that will very easily take you right into the centre of the old part of town in 10-15 mins. The apartment was clean, stylish and I felt comfortable during my stay there. Markus (who is looking after the place while Christian is oversees) was flexible with my earlier check-in time and very helpful with my questions about anything from transport, recommendations and laundry. Would recommend to anyone looking to stay in Vienna!
