Emmanuelle: We dont speak french but from (Hidden by Airbnb) translate this review states something like that "the apartment is old and needs to be renovated":
Thank you for pointing out that ours is one of the most beautiful antique Viennese apartments available for rent in Vienna with features like an antique Boesendorfer grand piano, chrystal chandeliers, and Vennese style curtains and woodwork.
The apartment is 150 years old, and we try to make the antique style clear in the photos. We have had several photographers and videographers rent our apartment specifically because of its old Viennese style.
Additionally the kitchen was recently renovated in the past 2 years with top of the line decor and appliances, and the front entrance room was renovated less than a year ago. A few months ago we had all of the windows replaced with brand new windows, and the entire apartment was repainted in the past few years as well. So while the apartment has an antique viennese style, we have also try to keep it up to date as well.
