Our stay at Alessandra's place was great! It is a very small studio, but was fine for 2 people. It has a comfy bed, a little living room and the hot plate in the kitchen allowed us to cook some meals which was awesome. The bathroom is also very clean and the shower was nice and warm. The studio is in a very secure building and Alessandra lives right next door if anything is needed.
The only thing I would say is it is a bit of a hike to the nearest metro. We literally walked everywhere in Rome (to all major sights) so this wasn't an issue for us, but it could be for someone else.
All in all a great little place to stay, good value for money in a pleasant a area of Rome.
