My stay at this Air B&B was the best experience I've had so far. Everything you read in the description is up to par or better. There is breakfast laid out every morning, more than enough to get the day started, including a thermos full of Italian espresso that stays warm late into the afternoon. The bathrooms, bedrooms, and common areas are all kept diligently clean. The beds are super comfortable and the shower actually has decent water pressure and a legitimate hot to cold gradient.
Regardless of how long you intend to stay, the vast array of seemingly arbitrary art and trinkets is definitely worth taking a look at as Giulia has been to many places and has an eye for bringing together, in style, this conglomeration of memorabilia.
Also, it would be to your advantage and benefit to strike up a conversation with the hostess as she is well versed in everything Roman, with her speciality being the cuisine and great authentic restaurants, to knowledge of all the sites in Rome. Great sense of humor and easy going bubbly personality that makes staying in someone else's home much more comfortable and welcoming.
In short this place has the expected amenities, as well as all the intangibles to boot.
