This is a great little apartment right in the heart of Rome. Easy walking to ask the main sites and, yes, the Trevi Fountain is right at your door.
Only 2 slight demerits. 1. Getting the key was a bit circuitous. You need to go to a hotel to pick it up and then go to the apartment. Not ideal with bags and taking two buses. Wouldn't want to do it after a long haul fight. 2. The proximity to the Trevi Fountain means there is lots of noise. The windows do not block much of the chatter, laughter and general crowd noise of the masses that surround the fountain.
