Everything was exactly as described. The apartment was well equipped, fresh and tidy, bright and quiet with beds exactly according to my preference ;) ... Even better, the apartment is within a pleasant walking distance from the old Vienna, in a quiet and safe neighborhood and a Park+Ride garage not that far away.
The owners were welcoming and provided us with lots of info on the local restaurants, markets and amenities, and answers to any question we had. At one point, due solely to my error, I have created a misunderstanding regarding the cleaning fee, but the owners reacted immediately and resolved this misunderstanding in the quickest and the most efficient way imaginable.
Next time we go to Vienna, I will try to book this apartment again. It felt like home!
