The apartment far from city center, ~30 min by bus, but in good area.
Paola was very nice in communication and fast responsing. We had early check in, and there were no problems.
Paola left DETAILED (if you try to stay here, you'll understand why I wrote this by upper letters) instruction for eating and transportation.
Some things to note:
1. Paola will ask you personal information, including Passport, it's OK I guess, but it was confusing first because it was first time that we were asked to give personal information by AirBnb host.
2. If you arrive early, Paola recommend to wait in nearby cafe. Actually, it's not so near to the apartment, so if you are with luggage it's not so comfortable to walk there. In 5-7 min walking it's MacDonalds, where I advise to wait.
Despite of this, we highly rate our stay here and surely recommend it to all Rome visitors.
