Apartment is indeed less than 10 mins walk to the Vatican. It has everything you need and a huge patio to eat in. There's a Carrefour express that we bought some of our dinner ingredients and the cafe across the apartment woke us up with their espresso and friendly service. I really have a good stay at Britta and Bruno place and Bruno dad was very nice to wait for us and help us to move the car around.
Britta even took some time to give us tips of going around the city and visiting the famous sites.
We will recommend this place.
