Giampaolo's apartment is in a fantastic position, at a short walk from St Peter's and the Vatican Museum. The area is very safe with plenty of shops and restaurants nearby. The metro is only 50 minutes away, giving easy access to all the sights, but we also walked back after dinner with two children from campo de fiori / piazza Navona via ponte Sant'Angelo and they loved it.
The apartment itself is very well decorated and has everything you need.
Giampaolo was very friendly and helpful.
