In the heart of historic Rome, on a narrow cobblestone side street off Piazza di Pietra, the iconic entrance to Salotto 42—a beloved lounge bar facing the ancient Temple of Hadrian—is framed by a magnificent cascade of vibrant purple bougainvillea. Bicycles rest against the wall, potted plants flank the door, and warm light spills from within, inviting passersby into one of the Eternal City's most stylish hidden gems.
