My two daughters and I had a great stay at this clean, bright, and practical apartment. The location is perfect with several public transport options within 5-10 minutes walking distance. The Mariahilfer Straße (main shopping street) and all of the historic buildings and attractions in the city center are easily accessible and there is even a super playground right down the street.
Check in and out were fast and easy, communication super. We would definitely stay at this apartment again on a next trip to Vienna.
