We had a great stay at Cristiano's place! Perfectly located next to Vatican City and Castel Sant'Angelo but also very close to public transport and the Hop on and Hop off bus stop.
We couldn't fault the apartment: very clean, safe and organised. Cristiano was very helpful in letting us know the best way to get from the airport to the apartment and also gave us some restaurant recommendations for when we were tired after a day of walking around and wanted somewhere we knew would be good.
Highly recommend!
