The flat is very conveniently located near the Westbf station (within 5 mins walk), which is a station connecting both the international railway network as well as the city metro. Despite being at the heart of the city, it is very quiet at night and you could have good rest after the whole day city visit.

Peter and Katharina are very nice and professional hosts who provide us with all the necessary maps and city guides to explore Vienna. I would highly recommend this flat to anyone.

Cheers
