Daniele attention is great, he is a nice guy that gave us good tips of places where to eat and visit.
I had only contact via email with Eugenia and she was responsive.
The apartment is located in an excellent place and neighborhood, you can walk to all the interest places (40 mins to "Vaticano" ), but there is always chance to pick a taxi at any moment.
The apartment is beautiful, tall and spacious for 2 maybe 4 people.
Cons.
Only one room for 2 people, 1 sofa bed for 2 people and another sofa bed For 1 people ( maybe 2).
The sofa beds are uncomfortable that we couldn't sleep well, in addition of a strange itchy that we get all nights when going to bed.
I'm sure that the sofas and beds were very dirty and not had been cleaned in a long time.
In our last night in Rome in Eugenes apartment we had heard to many noises behind a door near the kitchen, like animal sounds (cats, rats, don't know and we didn't open the door to investigate) I had contact with Daniele to asked him about the sound and he had confirmed that there was not a chance to be animals in the apartment, we could get to sleep around 1 am after all noises had stop.
