The apartment is perfectly located, next to the fori romani. Rome's main attractions are walking distance. The apartment was clean, well equipped for two people, still ok for a family of 4 with young kids. Not good for a group of 4 adults, in my opinion (too small). You will find a functional kitcken, a bed that is confortable, a sofa-bed that works for small kids (ours are 7 and 5). Television, stero, and WiFi. The place is NOT ok for people with mobility challenges, as to get to the bed you have to climb a steep ramp of stairs. Aside for that, the place is fantastically located to explore Rome. It is not luxurious, but functional. Nearby there is a grocery shop where I got one of the best prosciutto (and cheese) in Italy. Very handy after a day of sightseen. On the same road there is a pasticceria (a sweetshop) that we loved.
The seems to be nice (on the phone) but we have never seen him. He does not pick up the phone often, and does not answer messagges according to our experience. So, it is better to arrange for check out and check in in advance, as he is not available. For example, we needed t check out earlier than expected (at 9 instead than 930) and we had no idea to whom leave the key. Eventually we just left it under the doormat.
