Hotel San Pietro
Tucked behind the beginning of Corso Umberto I, this pleasant boutique hotel has a soothing lobby and a large bar area filled with plush sofas, antiques, and Art Nouveau works. Some rooms are a little on the small side, but are comfortable and airy—the larger, superior rooms have balconies. The hotel's best feature is the roof, where there is a bar and where breakfast is served, with great views of the dome of next door's Basilica of Santissima Annunziata Maggiore.
