O & V were wonderful hosts and there rooftop loft is a really interesting, accessible, and cool place to stay. We were greeted warmly as guests and all of our questions about the neighborhood, city, and transportation were answered accurately. The room is very nice and it would be great for a business stay as it has a washer, dryer, desk, and reading chair. I would recommend O & V to all travelers, especially couples, business travelers, and anyone looking to explore Vienna. Vienna is a wonderful city!
