I stayed 5 nights with Alessandro in Roma. His mother kindly accommodated an 8PM check in and as I was early I enjoyed a pizza and tiramisu at the pizzeria (la routina?) just 2 doors down. The flat is nice with high ceilings compensating for the more closed floor plan. I LOVED the bed - a queen sized bunk bed with a sitting area in place of a lower bunk. Very comfortable and cozy. The hot water is temperamental - I think it's best if you run it for a minute first thing in the morning and take a shower an hour later or so. I walked extensively through the surrounding neighborhood which is pleasant with at least 5 gelaterias and additional pizzerias as well. There's an atm across the street and it's a reasonable walk to the Vatican and the center.
Ultimately, I would recommend this flat if you want to stay in a slightly laid back neighborhood, away from but not out of reach of the tourists.
