Sounds like weather is a big factor.
Camarillo is a bit cooler in the summer than TO and Westlake
But both are a lot better than the San Fernando Valley, the area east to which I believe you refer.
As long as you stay in Camarrilo and not go into Oxnard there are not too many problems.
If the commute is only to Westlake Village, the 101 commute up the grade from Camarillo isn’t too bad.
As another posted, Moorpark and Simi Valley are slightly less expensive alternatives but until they finish the HWY 23 widening project the commute to Westlake would suck. Also, the weather there is a bit warmer in the summer
If the child is of school age, the schools in general in all of the above ar OK with some areas being a little better than others.
Good luck finding a reasonable price place to rent. $2000 seems a bit on the optomistic side.
