Very happy stay, the place is very clean and spacious, we would like to be back again.
location: perfect, you can walk to city centre and Schloss Schönbrunn by walking, around 2.5KM to each;
Facility: it's so nice for 4 people to stay, 2 separate bedroom, with full kitchen, 1.5 bathroom. With aircon
Host: communication with Caroline is smooth, she is very responsive and helpful.
Two things maybe helpful for others
1. if you drive, remember to buy parking ticket from Tabrik or subway station. You can find a public parking place but no machine to buy parking nearby at all;
2. There is a tax associate with the stay, around 2.5% of the fee.
