The apartment was very spacious and clean! We were there with 3 little kids and there was plenty of space for them to play and relax. The apartment is about a 20min walk to the Colosseum but you have to take public transportation or taxi to other attractions. There is a train about 5min away from the apartment so that's good for getting around the city. If you're someone who is comfortable with public transit and comfortable not being in a touristy area, this apartment is ideal. Check in was easy- Maria's housekeeper was there to open the door for us and tell us about the apartment.
We were there in November so the city wasn't as busy as it would be in the summer time- great for visiting the main attractions like Colosseum and Vatican.
