Christian and Jane are amazing hosts. You have everything you need in the apartment. Everything is very clean and beautiful. It is just about 10-15 minutes walking to the city center.
Christian gave us good tips about places you have to see when you are in Vienna, nice and cheap places to eat, etc.
Oh, and there were cake, orange juice and milk in a fridge that he bought for us. And it was very good because we were tired and hungry :)
We will definitely stay here again on our next visits of Vienna
