Great location, anything you want to do and see in central Rome is within comfortable walking distance. Especially helpful was the access to mobile wireless connection that Agostino provided, allowing access to any online apps you might need while on the go in Rome. Agostino was flexible to receive us at a late hour and was very helpful, especially in regards to medical problems that arose during our stay.
The apartment is basic but has most things you might need during your stay, could use minor maintenance. If you are staying more that couple of nights you might want to consider requesting extra set of towels. If you are a light sleeper you might want to bring your earplugs as the loft is close to a busy main street.
