My girlfriend and I stayed at Alessandra's place for 3 nights. The appartement is lovely, the location is great : close to Pantheon and Piazza Navona.
Alessandra was welcoming, her instructions were simple and clear.
The apartment was clean (pictures are very representative of the actual place). Breakfast (coffee, tea, muffins) was offered which is a nice attention.
Tall people be careful the shower can be little if you are over 1m90.
The bed was a bit too firm for a 3 nights stay and shower gel would have been appreciated.
Appart from this two specific points everything was perfect.
We would definitely recommend Alessandra's place for a Roman holiday ;)
