Right off the bat, we would have given this place 5 stars. The place, as we were told, is more than 300 years old, but was updated nicely. However, do note not to use both A/Cs, the TV, and the washer at the same time since that caused a power outage. Ambrogio and Giorgio were very responsive and got everything back promptly after a few texts back and forth. The location was excellent and was great for our family of 4. Comfortable walking distance to the Vatican, Piazza Navona, Trevi Fountain, etc. The walk to the Colosseum is a bit far, but if you hit tourist sites along the way: Pantheon, Vittoriano, etc. the walk will be a breeze.
Our only knock on the place was that the neighbors asked us to quiet down our kids who were laughing (not banging on the walls, not banging toys) at each other. They said that they needed to sleep (at 9am!). Our kids (5 and 4) were mindful enough to lower their voices, but we were not pleased as this is their vacation and the ask was unreasonable at 9am. Overall, we would stay at this place again, but will ensure to note to Ambrogio to discuss any issues with the neighbors beforehand.
