Giampaolo is very kind and very helpful! He organised taxi for us and gave us tips that made our trip comfortable.
The apartment is very close to Vatican city (less than 3 min to Vatican museum). Metro is also near by. There are restaurants and supermarket near by.
The apartment itself was very clean and tidy, equipped with all facilities (like kitchen, utensils, dishwasher, washing machine, towels, Internet, printer etc). The locality is very safe. Total value for money!
