Hotel B, with its impeccable design and impressive art collection, has raised the bar for boutique lodgings not just in its neighborhood of Barranco but in Lima as a whole. This restored Belle Epoque mansion, a former seaside retreat turned Relais & Châteaux property, houses 17 beautifully appointed rooms and suites, fusing carefully sourced vintage pieces with contemporary fittings. The ambience manages to be both sophisticated and homey. Organic toiletries, 300-thread counts, and oversize towels are the norm, and attention to detail is key. Take breakfast on the central patio or kick back on the ocean-facing sundowner deck. Service knows no limits and there's no lack of art, either: the hotel is connected to Lucía de la Puente Gallery next door.
