It was very easy to book the apartment with Natascha. Her replies were always quick and to the point and her place is very lovely. It is located very close to Westbahnhof, which makes it easy to travel anywhere in Vienna. The place is not big, but has everything necessary including a fully equipped kitchen with a coffee machine. Especially helpful was the binder Natascha had made that suggested cafes and restaurants in the neighborhood, had information on local transport and airport lines and also included a small map of the area. I would strongly recommend staying at her place!
