Yes, The Grand Budapest Hotel is excellent which is quite rare for a newish film in my personal opinion.
Is Downfall the film that the Hitler parodies use clips for?
Yes it is, don't get me started on Peacock Place!
Grand Budapest is a continuation of great films by Wes Anderson. Moonrise Kingdom, The Life Aquatic with Steve Zissou and Rushmore all fantastic if you love the aesthetic cinematography of Budapest.
