Xiao was very flexible with us both for our check-in and check-out. We were on a long trip so it was a bit hard to know when we would get there very long before actual arrival. Then, we went over the check-out time and he was gracious with us.
The place was very clean and modern. It was perfect for my wife, 2 kids, and I to stay there. Public transportation was pretty easily accessible. Xiao gave us great information for helping with parking, which is challenging in Vienna, but we managed it.
I recommend this place to others passing through Vienna.
