It was our first time in Vienna, and staying at O&V place truly perfected the trip. The apartment is located in perfect location, close enough to the city's attraction but still quite at night. Both O&V were great host. They were more than willing to help us with information about where to go and what to do. We trusted them for restaurant and bar choice, and it turned out just great! Also, they offered us super early breakfast as soon as they knew that we had to leave for early train. Would definitely stay here again if we ever have another chance to visit Vienna. Highly recommended!!!
