A stylish clean place, and Pietro is an easygoing and hospitable host.
Location is very close to the Vittorio Emmanuele Metro station, which takes you directly to Vatican - and with hectic public transport in Rome this is of great advantage. Other famous places (eg Colosseum) are also within walking distances. However, as the home is in close proximity to the main train station (another advanage), it gets quite unpleasant to walk in the area there at night, but no bad experience.
If you are looking for a relaxed stay - i would recommend
