We stayed in this appartment for 8 days and it was as comfortable as our own house. It was very clean and spacious and the facilities were more than enough. There was hot running water all the time and a fully equiped kichen. The apartment was a little noisy at night but when we closed the window and turned on the fan we were great. Also it's very close to the metro. We espacialy want to thank our hostess Oi Van who fulfiled every special request we had and answered every question we had instantly. We will definetely stay there again next time we visit Vienna and definately recomend this place to other travellers.
