You cannot beat this location and compact, well - equipped apartment. Everything is at your doorstep, but it is on a sidestreet so it is not too noisy. There is a little construction going on outside, but as I was out during the day, I was not bothered by it. Everywhere in Vienna, it seems, is under repair or construction! it is a 15 minute walk to the museum district - very pleasant and also to the main pedestrian shopping street, Mariahilfer Strasse.
The apartment has everything you need for a nice stay. Bathroom in particular, has been recently renovated and is very nice. I could hook up my Netflix account to the Smart TV. Communication with the owner was always very quick and pleasant. Love that the apartment was on the main floor - so no elevator or steps. It was very hot in Vienna for the 4 days I was there and the apartment remained comfortable throughout. Many older buildings do not have Air Conditioning and apartments can be uncomfortably hot.
I can recommend this apartment for your stay in Vienna.
