The name of this tiny hotel, located in bohemian and fashionable Monti, makes reference to the amount of rooms they have on offer. So, should you be looking for a homey stay in Rome, this might be the place. The property blends in discreetly with the surrounding residential neighborhood and it is hard to spot the golden sign on the outer wall, so be careful not to miss the entrance. The small lobby and reception areas are charming, with modern furnishings, vivid decorative tones and an overall cozy ambience. The welcoming atmosphere continues throughout the delightful common areas such as the room where breakfast is served and the nearby bar. A lovely tiny courtyard adds to the allure, so do request a bedroom facing it. Standard rooms are about 20 square meters (215 square feet), a generous size for European standards, and there are suites available as well. The Fifteen Keys is away from, yet still quite close to, the busy epicenter of Roman attractions, most being within walking distance. You will be four blocks away from hectic Cavour Avenue and a 10-minute walk to Santa Maria Maggiore, one of the most beautiful churches in Rome.
