Very close to Colosseum. Good instructions getting from airport to metro to bnb. Not too far of a walk from metro. Groceries nearby. Very clean, ac worked well, tiny minibar (fridge). Please be aware that Airbnb in Europe often times operates as advertisement for small businesses that rent rooms, as a business license is required to use it. Verify the details of their reception/staff availability (sometimes limited response) and other amenities (e.g. laundry facilities, kitchen availability) before you choose your stay. We were slightly disappointed by the laundry situation (not really described anywhere in the listing but there was a charge and it wasn't coin operated, so also confused about how to go about using it and no one to explain it). Also be aware that many old buildings have issues with their old locks and keys (we had issues with every lock in our building (even got locked out of our room for 20min), other guests had issues with locks as well.)
