"The steel-framed concrete skyscraper that contains the Hotel Warszawa was a marvel of Thirties engineering; today it’s charmingly historical, but what’s inside is ultra-modern even by 21st-century standards, with no attempt made to preserve its period interiors. Instead, it’s a luxury hotel in a high-design mode, containing industrial-style raw concrete and exposed ductwork in the public spaces, and warm textures of rough wood in the rooms and suites. An equally dramatic subterranean spa includes an indoor pool and a salt cave; the flagship restaurant is a tribute to the glory days of prewar Warsaw." - Tablet Hotels
