Nerva. Step out of this charming, clean, and well-run hotel and you'll feel like you're literally in the middle of an ancient imperial stomping ground. Strategically located a stone's throw from the Forum, it's surrounded by the breathtaking splendor of ancient ruins and relics. Guest rooms are on the small side, but modern: they're decorated with black-and-white prints of Roman monuments and statues, and have marble baths, air-conditioning, soundproofing, and orthopedic beds. If you pay in cash, the hotel will sometimes give you a discount.
