Stefan place was great. I was there for almost a week, the apartment was clean and stylish, comfortable and in a great area which was close to market with many amenities around. Train station is around 5-6 mins walk which you can take to most tourist landmarks in Vienna. Overall it’s a place I’d be happy to stay again and recommend to people. Stefan himself is very attentive and provided me with a lot of information about Vienna prior to my arrival.
