The loacation is very close to the train station and you can take bus to Metro station. bus takes 15min to the BATTISTINI metro station. that is my recomendation for ROME tour.
the apartment is 4th floor and elevator goes up to 3rd floor.
Francesca is very nice host and lives in 3rd floor. She is kind enough to give us late-check for catching the night flight. The tiny little minor thing is no wine glasses^^ Thank Francesca for everything!
