Sapphire House Antwerp, Autograph Collection

An early-17th-century building (renovated in the 18th, in the Rococo style), now with a 21st-century boutique sensibility. Part of the Marriott's Autograph Collection (emphasis on craft, design and hospitality), the five-star hotel (updated in 2022) has 139 rooms and suites, including some with 18th-century fireplaces. Authentic wooden floors, plus high ceilings, with prices to match. A "24/7-carat gym", but no pool. A 15-minute walk from the market square. A host hotel for Darklands 2025.
