We had a great stay here! The flat itself is clean, modern and cosy. It had all the amenities we needed for a long weekend.
Our hosts provided great communication and in the flat are loads of local recommendations.
It's a short walk to the ubahn, plenty of local shops and restaurants and the Naschmarkt is close too.
It's a slightly longer walk to the centre but not too far .
We would highly recommend if you're visiting Vienna!
