The apartment is 10 minutes of slow walk from Piazza San Pietro and well connected with public transportation, good coffee shop and 24h carrefour shop just across the street, pharmacy and a lot of little restaurants around.
It is a nice and cozy apartment that works more than fine for a group of 8 (even 12 as every room has an extra sofa), very clean and with all the appliances at your disposal.
Though i only spoke with Claudia on the phone, she was a great host, as she prepared everything for our arrival through her collaborators Gianluca and Marialuisa, both very kind and willing to help. They were all very receptive to our requests and made our stay very comfortable.
I would recommend Claudia and her apartments any time.
