Great location and very clean. The pictures were very accurate on the space. We were able to walk to the opera building in 20 minutes or you can easily hop on Tram 71 which was an easy ride Over to that area. The tram and metro were both only 5 minute walk. It was extremely warm in Vienna while we were there so it was a little hard for us to sleep because there is not ac, but he does provide fans for each room.
I highly recommend this apartment.
