Federico's was exactly as shown...better even. You can help but feel like you're entering a historical part of Rome; the steps leading up to the apartment, which have been worn over the years, the giant wooden doors...yet a completely modern interior.
A fairly central location, without having to be inundated by throngs of tourists the second you walk out the door. Several very good restaurants are literally right out the front door.
Federico was completely accommodating and even helped arrange a car to the airport for me.
I will definitely try to stay again, the next time I am in Rome.
