Our family of five loved staying at Caterina's place for a quick stop in Rome. Caterina contacted us a couple of days before with a number of different options to get from the airport to her place, and her husband met us at the apartment and helped with bags/stroller etc... We ended up walking from the bus station at Termini, which was a short achievable walk even with suitcases, day bags and small child in stroller. Nicollo then gave us advice on where to find a supermarket, its opening hours, and also recommended a lovely place for dinner which we really enjoyed.
The apartment was nice and spacious and have a lovely feel to it - was very clean and had everything we needed. The WiFi was super fast so it was good to FaceTime the family back home without any connection issues.
The location was pretty good - we were able to do almost everything by walking, including Colosseum, Pantheon, Trevi Fountain, Spanish Steps, Basillica di San Clemente (which I totally recommend by the way as an incredible site without big crowds). We did catch the Metro once and once again this was a very close easy walk.
