This property is wonderful both in terms of its interior and its location. Well appointed, incredibly atmospheric, and it wasn't just clean; it was spotless. It's in a quiet area that seems to be populated by well to do locals rather than tourists, yet two or so doors along is a beautiful church, at the end of the block are the remains of the Portico of Octavia and the Theatre of Marcellus (a bit like a miniature Colosseum), and then the Piazza Venezia is literally round the corner. The major sights are all within walking distance - we stayed five days and the only time we used transport was to get to and from the airport. You feel immersed in the local culture without it becoming invasive. There can't be many better locations in the city.
The owners were always where they said they would be and gave us every assistance with transfers to and from the airport: arranging taxis (polite and helpful drivers), making sure the cost was as it should be, and arranging our luggage deposit on the last day.
Can't fault it.
