This was a really nice stay in Vienna :) the apartment is not in the city center, but you can easily walk less than 15 min to reach Mitte and then explore the center of Vienna. If you have time, I recommend to do this walk by the canal. The place is well decorated and with all the amenities you need to feel at home. Big claps to the big shower and balcony! Kitchen has all the basics and the TV has the opportunity to connect to Netflix, YouTube, etc, this was perfect for the first rainy day. Down the street there is Ebi, a really nice sushi place, and around the corner a supermarket.
We would definitely come back :)
