This is a perfect spot in Rome -- close by the major sites (Colosseum, Palatine Hill, and the Forum) but not too much in the thick of things so it's quiet and a little more residential. Plus, you're close to the Monti neighborhood which has lovely cafes and shops and is a bit less overrun with tourists.
The apartment is very close to the train station, making it super easy to get to if you're traveling by train. I highly recommend the trains in Italy, and there's an easy train that transfers from Fiumicino to Termini.
Maura was a great host -- check-in was quick and easy, and she provided some favorite local restaurants for us to try (sadly, we didn't have much time to try them out).
The apartment itself is very spacious, well decorated, and comfortable. The shower in the bathroom is excellent, and there's a small kitchen that has everything you need for a short stay.
Highly recommend this spot for a great place to enjoy Rome!
