Renate is a wonderful host. She helped me with transportation, gave me great tips, heated me at the door with cold water after seeing I was overheating, and is just generally a really nice person. I was early and she made a special accommodation to allow me to come drop my stuff. Her apartment is gorgeous and in a perfect location. You can walk to everything. Even the restaurants right below the place are terrific with great service and food. There is no way i'll stay at another place while visiting Vienna!
