Best for bay-view suites, Mediterranean poolside dining, and design-led all-suite stays.

Best for a beachfront location, classic Art Deco character, and easy access to Collins Avenue and the boardwalk.
When Mondrian South Beach wins: choose Mondrian if you want larger all-suite accommodations with kitchenettes, a design-forward interior, bay and downtown Miami views, and a calmer, resort-like pool and dining scene focused on Baia Beach Club.
When Nautilus Sonesta Miami Beach wins: choose Nautilus if you need direct ocean access, prefer an Art Deco beachfront setting on Collins Avenue steps from the boardwalk and Lincoln Road, or want a more classically South Beach location.
Bottom line: both are polished South Beach options serving different priorities — Mondrian for suite space, bay-side calm, and a curated design vibe; Nautilus Sonesta for traditional beachfront access and the convenience of Collins Avenue.
