Thank you very much for your hospitality and promptitude, Patrizia! :-)
The flat is big enough for 6 people, clean, well equipped with almost everything you need for one week staying.
The flat it's very well connected with public transportation (both buses and metro) - you can be in Vatican in ~ 10 min. by bus.
You have at 5 min. walk a huge hypermarket where you can buy everything you need.
I strongly recommend Patrizia as a host!
