Giorgia's apartment was perfect for our group size (5 adults, 2 children). We had already asked for early check in but we ended up arriving an hour earlier than we expected and she was very kind enough to make her way to the apartment and still allow us in despite this. She also gave all the tips we needed for our trip in Rome which was very handy!
As we were travelling with young children, we did have to child proof the place such as putting away some ornaments in a cupboard during our stay but this wasn't an issue, just something we had to do to keep her things safe!
The apartment is not exactly close to the Colosseum and the main attractions (except the Vatican) but we are big walkers so we managed to walk everywhere (took around 1hr 30mins) to get to the Colosseum however there is a metro station about 10minutes walk from the apartment which can take you to most typical spots.
There is also a Carrefour supermarket just a couple of minutes away and open 24hrs a day which we found very good as we home cooked ourselves for the whole trip.
Overall, a very lovely and grand building to stay in. Lovely host, highly recommend. Just remember it is not in the very centre of Rome so you will need to travel in to get there but it wasn't a hassle for us even with children.
