It is a large apartment in a great location just next to U-bahn. It is 2 stops away from VIC and is very convenient for those attending a conference in VIC. It is also relatively close to Prater and to a nice playground for those who are travelling with little ones. And just 10 min away from the city center by U-bahn. There are several big shops just behind the corner, where you can buy everything.
Birgit is a super-host who replies and acts immediately when something is needed. We had a rather positive experience staying there.
