This is a great little apartment for those who want to be central to many of the main attractions of Rome. The apartment sits on a hill directly above the Colosseum, which is only about 5 minutes away by walking. Next to the Colosseum is the metro line, which can get you almost anywhere in the city you need to go and is fairly inexpensive and easy to use. The apartment is only 2 stops away from Termini Station on Line B at the Colosseo stop. Most of the other important attractions (Vatican, Trevi Fountain, Pantheon) are on Line A (switch is at Termini). There are several good restaurants and markets within walking distance of the apartment, many of which are on Via Cavour.
As for the apartment itself, it is on the second floor of the building that does have a small lift. It has two bedrooms with one double bed in each. There is also a sofa bed in the living room, which is fairly comfortable. It also has two full bathrooms, the first being in the master bedroom and the second in the hallway off the living room. It also includes a full kitchen and small dining room with most of the amenities one would need, though we did have to buy some more plates and cups as there were not many of each. It also includes a small patio that doesn't have much of a view of the city, but does include a table and chairs if you would like to eat outside.
Giovanni was very helpful and responsive if we had any questions prior to arriving in Rome and even set up a taxi to pick us up from the airport (50 euro flat fee).
Overall this is a solid apartment for a family or a small group of people traveling together. It is centrally located near one of the biggest attractions in the city and the metro. I would definitely recommend it to anyone traveling to Rome.
