the apartment is great, stylish and clean and very convenient to reach and centrally located and in a cool area. you can easily walk to the city centre. i didnt meet wendelin personally but had to pick up the key at a nearby bar, which worked without problems. wendelin was always helpful and responded quickly, for example when the heating didnt work at first, which he could fix via an app. wlan worked very well. only the mattress of the bed was a little bit too soft for my taste ;)... i can highly recommend this place if you visit vienna!
