Waltraud's place is really great and cozy. It has everything you'd need. The check in process was really smooth and especially nice since we came really late in the evening. It is really great if you come by car because the garage is easy to use and saves you money as parking in the city is expensive. The metro is about 5 minutes by foot and it is really easy to reach the city center. The neighborhood is quiet and easy to find. Also, there's a supermarket, a coffee/bakery and some other food options nearby. We would 100% stay again here next time we're in Vienna.
