Werner's place was an excellent home in Vienna for a week. The room was neat and clean, the bed was comfy, the windowshade was effective, and the desk was helpful.
I was very happy with the location. I walked into the city every day to eat, explore, and visit the library of the Gesellschaft der Musikfreunde (the official purpose of my visit), and the walk was easy and pleasant. It's also a short walk from the train that goes to and from the Vienna airport.
Werner was also an excellent host. Communication was good, and check-in was easy. Throughout the week, Werner spent time showing me around the neighborhood and around important historical and tourist sites. He also gave me some great restaurant recommendations, and lent me a card that allowed free entry to various museums, which probably saved me 50 euros over the course of the trip.
