I booked for my family and this is their comment.
Luigi was really helpful and kind, particularly for the arrival from the airport late in the night.
The apartment was really comfortable for four people and really well equipped. The air conditioning was appreciated during the hot summer week.
It was really well situated with good restaurants, shopping around and a supermarket.
It is situated close to piazza San Pietro which can be reached by foot and close to public transports and other parts from Rome are easily reached.
