Harald and Karola go out of their way to make you feel at home! They always responded to our questions very quickly and in a friendly way.
The apartment was very clean, the beds were very good and there were plenty coffee capsules and toiletries.
I would highly recommend this place. It may be bit out of the city centre but that also means it’s authentic :) And with Vienna’s marvellous public transport system you’re close to all main sights.
