Once the home of the king of Naples, the Palazzo Caracciolo now houses an upscale boutique that is part of the MGallery Collection of Accor Hotels. The stylish, contemporary interiors are a striking counterpoint to the historic architecture. The 139 rooms feature all-white decor with silver accents, modern bathrooms with black and cream tiling, and solid amenities, such as flat-screen TVs, stocked minibars, and free Wi-Fi. The lovely cloister is a favorite among guests for a quiet drink at night, and the Mediterranean restaurant is a solid pick for those who wish to sample regional cuisine. But the fitness center is off-site, and guests have to pay a fee to use the facilities. While its central location offers easy access to the historic parts of Naples, the hotel’s immediate neighborhood is somewhat dilapidated and feels dangerous to some.
