Good location, close to Belvedere and the Vienna Rennweg train station, which takes you to & from the airport in 20 min. Also, plenty of coffee shops & restaurants nearby.
The apartment is perfect for 4 people, but can easily accommodate 5. You will also find pretty much everything you need. Everything was very clean & matched the pictures.
The check-in process is very simple & we had no issues.
Highly recommended!
