If you are looking for an unique house that is located in a wonderful and convenient location, Ann's house is the perfect choice. The house is inside the famous Donaupark and very close to the Donau TV tower, one of the landmark building in Vienna. The house has a very nice yard. It is a very good place for relaxing. It is also very close to public transportations. Ann is a very nice host. She personally waited for us at the house for checking in although we were late. She provided a lot of useful information about the neighborhoods and the Vienna. Strongly recommend if you want to spend nights in Vienna.
