Great stay at Cristiana's! She greeted us during check-in and gave tour of the unit, gave suggestions for good restaurants and such. And there's a very neat file folder containing every single info you need about the equipment in the house, as well as for exploring Rome.
Location-wise is perfect, surrounded with plenty restaurants, you can choose to dine at those posh ones or where the locals eat. There are 2 grocery stores within 1 min walking radius, and 2 mins walk to Colosseum.
For transportation, 1 min walk to taxi stands, 3 mins walk to the metro station.
All in all, we had a very nice stay and highly recommend this place to others! Thanks Cristiana!
