Bernd is a very nice host. He responded always very quickly to our questions. We checked in the apartment by ourselves without meeting any problems. The house is very clean, comfortable and convenient. It's enough large for two persons. Although it's a little far from center city, It's just 3 minutes walk to the subway and train and 15mins to center city. It's very quiet in the night. I love it and very satisfied about the trip in Vienna.
