Claudia’s place was really great. We stayed there while it was hot and so had to keep the windows open - be aware that the bakery at the street level can get really noisy early in the morning, but it is nothing earplugs can’t fix. This place is less than a 5 minute walk to Praterstern station - it was SUPER convenient to get anywhere in Vienna from here, including the train station and airport. Vienna is really lovely and this was a great spot to stay.
