Leonardo is very helpful and nice guy, and we have good contact.
The apartment was clean and nice, there was good equipped kitchen, two medium size rooms and quite big bathroom (one minus is very small and not very comfortable shower).
Bed in room were clean and entire flat was prepared for us.
As well it will be comfortable also for four persons.

Only one disadvantage was certainly location and distance to center of Rome. You can take a walk to Vatican around 30 min and much longer to other attraction.

Leonardo thank you for hospitality.
