This apartment is in a great location! Vienna is an easy city to navigate - either on foot or by public transport, which was also very close to the apartment.
We visited in July when it was slightly warm, and we learned that most places do not have AC. We were initially concerned, but had no issues sleeping as the apartment had fans in each room and it cools down in the evenings. Don’t make that a reason to not book! We only wish we had more time in Vienna.
