I would not hesitate to recommend staying at Sara's apartments. Sara was a perfect host and made check in easy. It's a small simple apartment with everything you need for an uncomplicated stay in Vienna. Located in one of my favorite places in Vienna on Yppenplatz by the Brunnen Market (very colorful and multicultural with a fantastic array of good inexpensive restaurants and shops), one tram stop is just around the corner and other stops and the U-Bahn station is just 5 mins walk away. I'd stay here again next time I'm in town. Sara and Heimo, thank you!
