This spot really cannot be beat for proximity to St. Peter's and the Vatican, not to mention it's a very pleasant 15-20 minute walk from Rome's most famous sights like the Pantheon and Trevi. If you haven't been to Rome before, and are afraid of the public transport, I highly recommend this air bnb! Clean and comfortable, right next to a delicious trattoria, and less than 5 minutes from St. Peter's.
