The location was excellent for getting to the Colosseum, Palatine Hill/Roman Forum etc - also close to bus stops, the Metro and restaurants. The apartment itself is very clean with pretty much everything you need for an extended stay. Ample room for a family of four, and nice to have two generous-sized bathrooms. Our only complaint would be the noisy courtyard the apartment opens into - the locals like talking loud from about 7.30 am onwards, there are several dogs that start getting vocal early morning too, and if people leave the two door between the courtyard and street open - which seems to happen every morning - the street traffic noise also flows through. 50% of the noise was fixed when we realized the window above the entry door was open! However, overall we could recommend the apartment and agree with others that Salvatore was an excellent landlord who kept in great contact with us prior to our visit, and was very helpful and obliging when handing over the keys.

The owner, Salvatore, was super nice and helpful when we checked in. We didn't arrive at the apartment until 945pm (due to a trip delay)which was just before the cutoff of 10pm to check us in (per apt. bldg rules) and he had to go out of his way to meet us at that time. We stayed there 3 nights. Beds were comfortable and kitchen was well stocked with dishes and glasses but did not have a drip style coffee maker that we Americans so often use. It's not large but had plenty of room for me and my 2 friends. The smaller bathroom shower only had a trickle of water. I did notify Salvatore of this when I returned home.
The location is very convenient. We used the Manzoni metro station a few blocks away (to the left as you leave the building) since we heard the Coliseum station and line to Termini had a lot of pickpockets.
I would recommend this apartment since it was so easy to come and go.
