The upper-middle-range, six-room Hotel Trevi Collection is housed in a historic 16th century mansion, but its interiors have a modern, vibrant feel. Rooms have wood floors, flat-screen TVs, and clean-lined decor in shades of blacks, browns, and grays; even the standard rooms are large (particularly by European standards). Bathrooms are sleek, with double sinks, bidets, and either impressive walk-in showers or appealing shower/tub combos. (Though we did spot some water stains and rust.) There's no fitness center, but there is a nice, tranquil relaxation area with Jacuzzi tub. Free Wi-Fi and free breakfast add value, and the location near the Trevi Fountain and Spanish Steps is excellent.
