Four Seasons Hotel Gresham Palace Budapest
Faces the Chain Bridge, with Buda Castle rising behind it across the river.
The Art Nouveau palace at the Pest end of the Chain Bridge, and the only Forbes Five-Star on this list. Cruise Critic posters report Viking ships tying up directly across from it — a passenger report, not a line statement, but if the sail-in is why you chose the Danube, this is where you watch the river wake up.
