We spent some days in Domenico's appartment and it's realy as it looks on pictures... and 5' walking to te station to Fiumicino!
Just suggest to clean more the carpets and include in the final price, once you book via airbnb, the 45€ of housekeeping (otherwise can be a surprise when you've already pay the reservation... and we think they write it in the description, but anyway should be included).
We recomend it if you don't want to be at city center ☺
