Federico is great host! I booked the place for my parents, aunt and cousin (out of all only my cousin speaks english and no one speaks Italian) - Federico arranged transfer from and to airport, met my parents at arrival, showed the place and gave some tips. At the check out he was very flexible and helpful.
The communication was seamless and very easy from the booking till the check-out.
The place itself was very clean and exactly as described. Great place for 4 people.
Location is better than perfect as it is right round the corner from Coliseum. There is a supermarket 3 minutes walking and lots of places to eat.
