Four Seasons Gresham Palace — A Restored Danube Landmark

The Four Seasons Gresham Palace is the only Forbes Five-Star hotel in Hungary, and it earns the rating on the room, not just the address. The 179 accommodations split into 160 rooms and 19 suites, Art Deco-styled with marble bathrooms, and the best of them come with floor-to-ceiling windows over the Danube or the courtyard. The Royal Suite is the one to know about: an open-plan layout with its own dining table for four, and a panorama that takes in the river, the Royal Castle, and Fisherman's Bastion all at once.

The spa is a genuine draw on its own, not a hotel amenity checkbox. Seven treatment rooms, a couples' suite, an infinity-edge lap pool, a whirlpool, and separate steam rooms, built around the signature Touch of the Earth treatment using Omorovicza, the Hungarian luxury cosmetics brand most visitors won't have tried before. Downstairs, MÚZSA does a modern take on Budapest's Golden Age drinking culture in the lobby bar, and Kollázs Brasserie pairs French technique with Hungarian ingredients, river view included.

The building itself, an Art Nouveau insurance-company headquarters from 1906, restored and reopened as a hotel in 2004 after decades as a Red Army barracks and then a plain apartment block, is part of what you're paying for. But the reason to actually book it is what Four Seasons built inside that shell: consistently rated service, a spa worth a full afternoon, and a Danube-front position five minutes from the Chain Bridge that no newer luxury build in the city can replicate.
