It was a very clean and cosy appartment. The nieghborhood was very calm, fifteen minutes away from the Schonbrunn Palace, and straight to the center with tram !
We didn't meet Daniel because of the Covid in Vienna, but he perfectly organized our arrival in the appartement !
The only little nnegative point is that we can hear our neighbors in the other appartments..
Anyway, I really recommend this place for a stay in Vienna :)
