Me and my bf spent one night at Livianas place. It was close to all the tourist spots like Colosseum, Pantheon, Fontana di Trevi...we walked around about 2 hours. You can find great places for food in the neighbourhood. The room was clean and though we booked the same day Liviana responded quickly and we had no problem finding the flat.
Only thing: Wifi didn't work, but we didn't mind.
Thank you Liviana!
