We absolutely LOVED our stay here - the apartment was beautifully appointed, spotlessly clean and in a perfect location. The Metro is just steps away (although we only used it once since Rome is such a walkable city.)
Coco was kind enough to arrange transport from the airport, which made everything so easy, and her father Tommaso met us right on time at the apartment. Coco even stocked the fridge with some condiments and beverages, although we ate most of our meals in town - it is Rome after all :)
The photos don't do the apartment justice - it really is just lovely, with tons of storage space. There is some street noise in the area but the windows are very well-insulated when closed.
The only problem we had during our stay was unreliable wi-fi (it seemed only one of us could use it at a time) but this was not a big deal, we just took turns.
We will definitely stay here again if we return to Rome!
