Great location for walking to the sights! Check in was easy, very communicative and helpful. If you drive, there is a parking garage very close (valet style) so your car doesn't get towed overnight-- our host helped us with this. Also, the apartment is easier to find if you use the coordinates airbnb gives you directly rather than typing in the address, the apartment is through the same door as the British Institute of Rome.
It was a clean place to stay and a great location, good find!
