Its a great apartment. Two big and clean sleepingrooms and bathrooms.
Stefano is very kind and helpfull. If he can, he pick you up and bring you back to the AirPort.
I recomment this apartment to everyone.
The center of old Rome and Trastevere is about 20 min walk. The center of the Vaticaan is about 10 min walk.
Everything is nearby, supermarkt and restaurant GOOSE across the street.
A busstop that brings you to piazza de Venezia is on the other site of the frontdoor of the apartment .
