I'm sorry respond until now but I have limited access to the internet in my stay in Rome, I'm still on my way home, tomorrow in my computer I can sit down with some time and write to you the address of the places I went and I reccomend you to try.
Right I can say that for pizza al taglio Forno campo di fiori, Forno Riscoli, Panella el arte del panne and pizzarium are amazing and not expensive as I was expecting. But 00100 was just OK, expensive and there where not very friendly.
Tomorrow I add other places.
So I make a little map so you can see the exact location of the places [ Anonymized URL Blocked ]
Let me know if you use it, I hope this map can help you.
