Hungary

An opulent Art Nouveau landmark turned luxury hotel with direct views of the Danube and Chain Bridge, the Four Seasons Gresham Palace is repeatedly praised for elegant rooms, impeccable housekeeping and staff who go out of their way for guests. Expect classic grand-lobby drama, a well-regarded spa and breakfast praised by many — occasional complaints focus on pricey or uneven restaurant service.

Nestled in a former andesite quarry near the Tokaj vineyards, this striking adults-only design hotel pairs a mystic South American aesthetic with luxurious relaxation. Highlights include the extensive Amazonas Spa and a delightful resident sloth at reception.
