The Mozart apartment was excellent. It is located in a quiet neighborhood with easy access to the street cars for a quick ride to the Schottenring station for touring the city center. The apartment building is a beautiful structure from the early 1900s. Interior ceilings close to 4 meters high and chandeliers give it a historic flair. There is plenty of room to relax once back from a day of sightseeing. The master bedroom is very large. The second bedroom is smaller, but can easily accommodate an adult. There are sofa beds for room for others. Christian lives in the same building and was readily available to help. He was a very gracious host. I would rent this apartment again in another trip to Vienna.
