Tania was a fantastic host! The communication was superb. Tania met us with a warm welcome and was always available to answer any questions we had. The place was super clean and comfortable. The train is about a mile away but there is a bus right outside that will take you there. We were fine walking to the train and even with luggage it was walkable. If arriving from FCO, taxi service is around $50, which is what we did. However, you could take the train from FCO to Termini and transfer to the orange line to Battistini station (and walk 1 mile or take the bus to her place).
