FIrst of all, Ali was especially helpful in every way. The complimentary rides from and to the airport was really convinient, and everytime we ask any question he was guick and helpful. The location couldn't be better. You can walk to most of the destinations inside the Ringstrasse within 15 minutes. The Operahouse is right around the corner, and the Karlsplatz metrostation is right in front of the apartment.The apartment was newly renovated, so it is new, nice, cozy and comfortable apartment. I couldn't imagine a better place in Vienna. We would definitely stay here again if we come to Vienna one more time.
