Be prepared to travel a lot across the city, like the vatican, it is far, the trains are crowded, can't even sometimes squeeze in. Most tourist attractions are across the city she is just close to cafes, which are everywhere and local shopping. The host will bother you a lot, she will ask for more money, for the city per person tax, and she will want to have an exit walk thru to make sure that nothing is missing, that you did not steal anything. There are much better Air BnB in Roma, like try and stay near the Spanish Steps, or Trevi Fountain, you will enjoy it much more and get a nicer feel for ROMA
