The 40-room Regent's Garden Hotel in a Haussman-era mansion takes its name from its romanic garden designed by landscape architect Xavier De Chirac. Japanese-style, it is a tranquil refuge with fountain and rare plantings. It was the first Paris hotel to receive the Ecolabel and is fully committed to using organic products, including free-trade toiletries. Away from the bustle, it is still a short walk to the Arc de Triomphe, the CDG airport coach stop and Parc Monceau,
