This apartment has beautiful artwork, lots of light and a perfect location. All of the people we met (Luigi, the drivers, the housecleaner) were very nice and helpful. We were grateful for the late-night pickup at the airport in Rome, all of the shuttle service was perfect. If you are looking to be right in the heart of the Colosseum area you can literally not get closer to the attractions and it was easy to navigate the Palatine hill and Roman forum from where we were staying. The area felt very safe, and there is excellent food at the Pasqualina restaurant right around the corner.
That said it is a small place, the water in the shower does not get very hot, and the refrigerator was broken during our full stay (which management knew about before our arrival but did not inform us about). The kitchen is very tiny and not ideal for cooking in. So, if you are a group of friends or a couple looking for a fun location with great local attractions and food this place will work really well for you... but in our situation (as a family with 3 kids) it was not ideal. We would probably go somewhere else in the future.
