Our stay at Claudia's place was perfect.
The apartment is spacious, airy and was comfortable for our group of five adults.
The location is very central. About a twenty minute walk to main tourist attractions and five minutes to the underground as well as a main street filled with shopping and restaurants.
Check-in was easy and effecient and Claudia was very responsive and helpful to all our requests.
Tip: bring your own shower soap.
Would highly recommend this apartment - will definitely book it again when we next visit Vienna.
