Very nice place to stay, "a place with a soul", unique. Good location, very close to Mariahilfer Strasse, no far from center (20 min. walking). It was clean, well equipped, we haven't been missing anything. Big advantage is also a parking place close to appartment. Defintily would come again. We haven't met Helena in person, but her friend Laman, who picked us up, was very nice :)
