Ulrich's place is beautiful, quiet and very comfortable. The apartment is in a wonderful spot that is great for walking to the city center, and convenient for public transportation. I've spent a lot of time in Vienna, and this is a great location. Plus there are nice cafes and bars within a few blocks. The bedrooms are of comparable size with super comfy beds, and the apartment was sparkling clean and very well maintained. We had a small problem getting in because the key was not in the right place, but the situation was quickly resolved. And in all due respect, Ulrich had arranged for us to have an early check-in that worked well with my overseas flight that arrived that morning. HIGHLY recommended and I would gladly stay there again.
