Our stay was perfect during our trip to Vienna! The apartment was better than we expected and the host was very helpful during our stay.
The location is super convenient if you are traveling into Vienna by train. It is less than a 5 minute walk from the main train station in Vienna. From the apartment, the city center is probably anywhere from 20-25 minutes. But, we pretty much used only Bolt/Taxify and the U1 train to get to the city center. Which gets you there in about 10 minutes and is pretty affordable if you get a day pass.
The area around the apartment always felt safe and had plenty of restaurants/cafes to grab something to eat before heading out for the day. So you shouldn't have any issues finding something to eat around the apartment.
We highly recommend this apartment to anyone visiting Vienna!
