I have lived here for 20 years . The best nighborhoods in Temecula are goone be obvious its funny but true. The old torn down neighborhoods that look bad are the ones were the drugs and the poorer people live. Unfortanetly there is some of that here not as much as orange county. French Valley is a new nice community and quiet up off Wichester rd , Thers nice homes around Crown Valley off Highway 79 . Theres older homes but nice neighberhoods off Margarita in Ridgeview I think its called houses off yakee run street its called across from Temeku Hills houses . I hope I helped.
