Book well ahead for La Piccola Maison, a clean-lined small inn in a 19th-century palazzo near Via Veneto’s glam boutiques and caffes. Its pale-toned furnishings and sparse design offer a welcome respite from the colourful street life down below, a few steps from La Dolce Vita’s Trevi Fountain.

In the middle of the historic center, you will find La Piccola Maison, a small, elegant hotel in a sober style. The white and beige tones work relaxing and that is very nice if you are in the heart of busy Rome. Many of the sites are just a few minutes away.
