We Hostel, Sao Paulo
This new design hostel stands inside an early 20th-century mansion in the Vila Mariana district of Sao Paulo – Brazil's largest and liveliest city. Inside there's one private double, with cable television and a huge balcony, and a range of dorms that sleep between two and eight people. For female travellers, there's a women's-only option, with a private bathroom. The tone throughout is simple but stylish, with metal-frame beds, shuttered windows and wooden floors. But it's the shared spaces that really stand out – with vintage sideboards, eye-catching art prints, mid-century sofas and an industrial-style communal kitchen that opens on to a courtyard. Outside, the restaurants of Rua Joaquim Tavora and the lush green pastures of Ibirapuera Park await.

Castelinho38, Rio de Janeiro
This small hotel offers outstanding views of Rio's coast from its hilltop perch in the Santa Teresa district. Housed within a two-storey, 19th-century building, it hides 12 spacious rooms with colourful quilts, period furniture and abstract artwork. Start the day with tropical fruits and homemade bread, before exploring the neighbourhood's cobbled streets, ageing mansions and bohemian bars. Come afternoon, retire to the tree-shaded tranquillity of the hotel's terrace, which looks down across the Baia de Guanabara.

Marica B&B Foz do Iguacu

While in the area, base yourself at this downtown B&B, which has four homely rooms and hearty breakfasts. Aim for either the purple-painted Lavanda suite or the nautical-inspired Ocean, which features sea shells and pillows printed with fish.
