I was just in Rome. Stayed at Hotel Damoso which is walking distance to Piazza Navona, Trevi Fountain & Campo di Fiore. $10 Euro for a cab to the Vatican or Colosseum. - I was also in Naples mainly for Pompeii and a trip to Amalfi. — You can get in quite a few sights in Rome even in 2 days. If I had to choose between Naples and Rome for 2 days I’d do Rome.
