In a neighborhood with a lot of overpriced, underwhelming hotels, this above-average boutique option, in an 18th-century building minutes from Trevi Fountain, is a good value even in the summer. What rooms lack in size they make up for with sleek modern design and spotless bathrooms with mosaic tiles (two rooms share a bathroom). A fifth-floor covered terrace is the setting for an ample breakfast buffet with lots of home-baked goodies, as well as evening cocktails and occasional happy hours.
