We highly recommend the apartment! It is large (with big balcony), very comfortable and nicely furnished. It was also very clean and everything was in place. The location is very convenient, right next to a subway and train. There are a lot of shops around which we loved. And the owner was very responsive and cooperative, he made our arrival to Vienna and stay at the apartment incredibly easy. Oh, and the air conditioning made our life way easier during those hot days. We loved it!
