Nau Royal Hotel Boutique & Spa

Tucked between Atlantic rainforest and the São Paulo state coastline, this 13-room boutique hotel makes a quiet case for the stretch of Brazil that gets overlooked between Rio and São Paulo city. Rooms run from garden-view with hammock to an oceanfront penthouse with a Japanese soaking tub. The L'Occitane spa and a candlelit deck for caipirinhas take care of the rest. Adults only, two-night minimum, and somehow that all sounds like a feature.
