I unfortunately was an hour late for checking in ; Irina still was really helping and welcoming.
The flat is exactly as described and in a nice and very practical area of Rome : typical Italian coffe for breakfast at 10 meters ; ice cream shop at 5 meters ; supermarket at less than 100m.
The historic center is so close that I took the metro only one time and walked the rest of the week end.

the kitchen (shared with two other rooms) is huge and well equiped. I stayed for two nights but you could clearly consider staying for more in good conditions.
