A Hotel in a 5-star-location: Whoever is a guest at the Kärntnerhof measures the distance in meters and the walks in minutes.
Most of the things you wish to see can easily be reached by foot. The Imperial Palace? – a stone’s throw away. Shopping? around the corner. Art and culture? next door. For destinations that are farther away use the underground nearby.
Or take your own car from the hotel parking area.
