Piera is a very sweet and caring host. She actually came to the tram stop to pick me up. She is very thoughtful, trying to ensure that I get the best of Rome.
As for the house location, you cannot ask for anything better. Every place in Rome is closeby - Trevi 1.2km, Collesium and Roman Forum 2km, Vatican 2km, Pantheon 550m - could easily walk to each of these.
The rooms were neat and clean. There is a big courtyard as well, where I could work from and even practice yoga. Had many many cups of coffee and goodies - during breakfast and beyond.
Would love to come back to Rome and stay again at Piera's place.
