Beautiful hotel ,just south of Vienna, with really easy access to the city by taxi (although a little pricey) or by bus to the underground metro ,which is quite cheap & a great experience ! The Karl-Wirt rooms were spotless & the beds extemely comfortable. Breakfast was buffet style but had an enormous array of choice .It had its own restaurant next door with very friendly waiters who were very helpful. The food ,delicious too ! We will definitely stay here again.
