Gianlorenzo was there to greet me when I arrived and available throughout the week when I needed him. His place is well located in Testaccio, close to the metro and walking distance to Trestavere. If I had more time, I would have stayed my whole time in Testaccio. It's really a typical Roman neighborhood with way less tourists then central Rome. His place was clean and everything was there in the kitchen, if you want to stay in and cook for yourself with ingredients from Volpetti, Testaccio market, etc...
