Rocco is a great host: very considerate, super easy to communicate with, making his really best to help. He provides all you need for breakfast (cereals, milk), small bottles of water, yoghourts, coffee, tea. Feels very nice for breakfast or after a long day of exploration!
The flat is very well maintained, clean, with plenty of rooms to store one's stuff. It's also ideally located, 2mn from Santa Maria Maggiore. It is on the street, which was weird as the beginning: I could see people passing, hearing them talk, as they could not see me. It turned out to be fine: the street is not so noisy at night (better to take earplugs in case), I slept well (comfy bed!).
Will come back again!
Thanks Rocco.
