Need 1 room for family - temporary (Los Ángeles)

Hello.
! My name is Lucie my husband and I are looking for a room to rent in Los Angeles, Long Beach, Downey, Bell Gardens, Paramount or near by cities for 1-6 months.
I am moving back to CA from AZ and find it hard to rent a place from the distance.
I have 2 boys (9 & 11) and a small mixed dog about the size of a cat.
I need to move in the next 3 weeks so it’s a bit urgent.
Thank you for your time.
