This was a great apartment in a really convenient location right by St Peter's square (great for a late night walk and pictures with no crowds). The apartment was perfect for our family of 9 (6 adults and 3 children), the 2 bathrooms were just about right, the kitchen was small but perfect for breakfast and the odd dinners when we wanted a night in.
Alessandro very kindly left us lots of supplies when we arrived (bread, milk, coffee) and he was great in arranging airport pick-up for those that arrived very early and kindly let us leave our baggage for the last day of sightseeing.
Location wise the apartment was perfect for walks/jog in to central Rome, but also really well connected with the metro and buses. We preferred the bus in the last few days with our tired feet, there is a bus stop just down the road which takes you directly into town (no. 46 and 64 to Piazza Venizia). When you come out of the apartment turn left and head up the hill for the local train station (train to fiumicino airport - need to change trains though), and local supermarket - en route there is a great view of the city. Walk further out from the main road for some great local restaurants.
