Christa's penthouse apartment is outstanding. It has every amenity that you could possibly want plus more including a bottle of wine and chocolates. One of the two balconies overlooks a small park with lots of trees. A Gusthaus with fine food and drink are across the street and another good restaurant is a block away. The subway, trolley ,buses and City Bike rental are all within three blocks. All in all a wonderful place to stay while touring Vienna.
