My husband and I stayed at Ella's for 3 nights at the end of a long hiking trip through the Swiss Alps. First off, the location is AMAZING. Walking distance (within 15-20 min) of most major sights, and the neighborhood (Nebau) is full of amazing cafes, boutiques, restaurants, and bars. We truly loved Vienna and will definitely be back. Second, Ella was really responsive and helpful, even let us store our bags before check-in while we explored the city on the first day! We loved the city, and Ella's place perfectly suited our needs.
