I can't say how beautiful is the Kunst in a short review. The building is a work of art, much prettier than anything you will see at the Schonbrunn Palace. The cafe will enchant you and you won't stop taking pictures. The Kunst has painting by Caravaggio, Van Dyck, Velazquez, Canaletto, Brueghel, the elder, etc. The museum costs 18 or 19 euros. It is a must-see world class museum. When you're there, look up. The ceilings are beautiful.
