Great location near the Colosseum - spacious, comfortable, clean, lots and lots of storage. Easy to use appliances and one of the best showers we've ever used. Communication was speedy and the one issue we had (missing dish towels) was responded to and resolved quickly. We also used Maurizio to book our airport transport and the drivers were timely, efficient, and helpful (and it was done super quick). We booked at the last minute for an unexpected two days in Rome and had confirmation almost immediately. Would definitely stay with Maurizio again.
If you want to be near the Colosseum, it doesn't get much better than this. There's a short walk to the Metro and the ticket booth / tour meeting points. Good restaurants nearby and a lovely little neighborhood to stay in - expect crowds due to the location but they do not impact the quiet of the stay and the balcony is still very private (with a fascinating view of the ruins the building is on top of).
