Giulia's place is fantastic for exploring Rome. It's easily accessible from Termini station via bus and the location is great - far enough away from the craziness of Rome while still being close enough to explore by foot. It's a 10 min walk to Vatican City and from there you could grab the hop-on-hop-off bus if you wanted. We took a cab (€15) to the Collosseum and spent the day walking back to Giulia's. The place itself is very clean, well-maintained, modern, and felt very safe. Giulia was responsive to messages and helpful throughout - highly recommend this place!
