Great location, decent sized rooms, and even better service! The location is perfect. You get to see the glorious Pantheon when you start and end the day. And the piazza is a great way to end the day. But what sets this hotel apart is the amazing service. We were taking the train to Naples, and Hotel Pantheon arranged for a taxi to Roma Termini. Unfortunately, we left a phone in the taxi. We contacted the hotel, and they immediately got in touch with the taxi company and driver and retrieved and held the phone for us. Amazing service and super helpful.
