How did the Fire of Nero impacted Rome in 64 AD?

Many authors wrote in history that Nero had a pivotal role in burning Rome in 64 AD. Somebody says that his love for Greece made him dreaming of having a new marble city, somebody else says that he blamed the Christians for the flames that burned in Rome for one week. It's unknown ,however, if Nero intentionally burned Rome. Recent excavations conducted under the arcades of the Circus Maximus confirm that the fire started from that part of Rome: in fact many shops in ancient Rome had wooden furniture and a torch may have caused the disaster. Nero later on was hated more by the Romans because the residential area occupied today by the Colosseum was expropriated to build his own new house: the Domus Aurea. After having committed suicide, the senate decreed the Damnatio Memoriae and all the portraits of Nero were destroyed or carved again with the traits of his successors.
