Alessandro was always easy to contact by mail. He welcomed us (11 people) at the appartment and gave us all the explanations we needed.
The appartment is very clean, like in fotos. Big flat, equipped kitchen, coffee machine, hair drier, soap, towel, linen, ...
Air conditioning in the living room and in each bedroom. Small balcony.
The road is sloppy, so the cars are making noise when going up, a little bit annoying during the night.
Easy to reach from Valle Aurelia Subway station (5mn). We also took the FR3 at this station (Roma's suburban train).
We went back from Vatican walking : 15 or 20 minutes.
Good wifi.
