We rented the apartment for 3 nights in July 2019. We are a family of four with two boys aged 12 and 21. From the 1st communication to the final checkout everything was perfect. Maurizio and his family replies rapidly and they really make an effort to help us out (eg by booking the airport transport for us). The apartment is really as splendid as the pictures tell, and certainly gives the feeling of luxury. Smart electric windows, a waterfall and a jacuzzi. Two separate bathrooms, one with an open glass solution to the shower (maybe not the most private shower then :-) )There is a queen size and a king size double bed. (Note that to get to the king size bed located a "mezzanine level" behind the TV in the living room there are some steps that can be a challenge for elderly people).
They were all there for our check-in father, mother son and grandchild, making the feeling of a personal welcome. It is mainly the son Gianluca that speaks good English. Chocolates on the coffee table! It is a new apartment so everything is in order and with the delicate detail of finishing in the photos. The windows are towards an interior backyard so there is not much of a view. TV channels are mostly Italian but we had Netflix available (logged on with our own account I believe - can't remember).
They have tips about restaurants in the neighboring Trastevere area (we tried them all and they were really good and with authentic atmosphere - low key and casual as we prefer them - and with good traditional food). Wish only that we had stayed more days - and certainly hope to get back next year! Warmly recommended!
