The apartment is in a fantastic area of Vienna!!
Naschmarkt, sightseeing points like Stephansdoom, a great selection of museums, shopping streets and so on and so on are very close by and easy to excess by feet or Metro. In the area of Opernring and Operngasse you can find food from all around the world ("Hausmannskost" from Vienna too of course) and the selection of bars and restaurants in any price range is enormous.
We are a family of 4 and the apartment gave us more than enough privacy if needed. It is very clean and has everything you need. The beds are very comfortable and the balcony was the cherry on the top. We thought about steeling that massive couch in the living room as the comfort it brought us in the evenings was great :)
Our host was always in communication with us and we felt well looked after. Everything was explained very good and super friendly.
We absolutely would recommend this lovely apartment and look forward to come again.
All the best, Johanna and Family
