Ancient meets modern at the 14-room boutique hotel overlooking the Roman Forum that has 2,000-year-old crypt on-site. (On-site! It's the only hotel in Rome that can make this claim.) The décor is contemporary, sumptuous and almost a little overdone, with curtains draped around four-poster beds, embossed wallpaper, and dramatic chandeliers. Breakfast and cocktails are served on the rooftop terrace, which has great views.
