The place is about 20 minutes from the city center or the main attractions. However, th3 connectivity is quite good, thanks to excellent tram network in Vienna. It's about 10 minutes walk from the nearest tram.
The neighborhood is not the liveliest at night. Being slightly in the outskirts, we didn't feel 100% safe to roam very late at nights. But that's only because we were a little cautions being in a new city.
The stay was comfortable. The terrace is absolutely lovely. We enjoyed a nice breakfast there. The apartment is good enough for 3 people.
