Our stay in Johann apartment was a wonderful experience. Johann is a very helpful host and ready to answer any questions quickly. The apartment is in a perfect location, everything is very close. restaurants, shops, museums, etc. Vienna is surrounded by old buildings and full of history, so be ready to explore. The apartment is also one of these buildings so there is no elevator so be ready to go upstairs. To be quite honest, this was just a detail, we enjoyed it so much that we would definitely come back.
