Great apartment and great host!
Francesca arranged for a van from FCO to the apartment (for 70 Euros) and showed us around when we arrived. The apartment is spacious and is located in the heart of Trastevere.
Through their website/app, AirBnb didn't include the cleaning fees (40 Euros) and occupancy tax (3.5 Euros per night/pp) which we paid in person at check-in.
I would recommend Francesca's apartment for anyone who's looking for a nice apartment while exploring Rome!
Grazie Francesca!
