Dada met me at the apartment and made me very welcome. She showed me all the facilities of the apartment and left me with some groceries to get me started for my week long stay in Vienna. The apartment is lovely - bright, clean, contemporary and well appointed. The neighbourhood is quiet with a shop and cash point opposite and a nice Viennese cafe around the corner (Cafe Wortner) - important to know when arriving on Sunday evening with all grocery shops closed.
The apartment is also one minute away from the U1 station at Taubstummengasse so easy access to the rest of the city - and also walking distance from Schloss Belvedere and the Naschmarkt. Fast WiFi also.
A great stay!
