We loved the Vatican Palace! Giorgia was very kind and met us at the flat after we flew in. There were many pros to this flat! The wifi is portable, meaning we were able to take it with us through the day (although the battery doesn't last the entire day) and as long as there were only a few of us connected at a time, it worked great. The beds were VERY comfortable and the six of us didn't feel too crowded in the 2 bedrooms and 2 bathrooms, plus the pull out sofa. We didn't cook, but there were bowls and spoons for our morning cereal.
The flat is farther from central London than we expected and about a 10 minute walk to the nearest underground transportation, you will most likely need a metro card of some sort to get around. This was probably the only drawback. However, it is within walking distance of the Vatican itself. The area looks more ghetto than it is... we're a group of university aged girls and we felt perfectly safe.
I would recommend this flat as long as you are willing to buy a metro pass (we bought a 3 day Roma Pass for 35 Euros)! It is nice and clean and Giorgia was wonderful to work with. It fits the description well! Great deal for the price!
