Location of Adjectives

1.  Usually the adjective comes after the noun in Spanish.

             la mesa negra  (the black table)

2. Adjectives are also placed before the noun to emphasize the adjective, expresses a subjective opinion. To highlight a well-known, evident, expected attribute of the subject

             la bonita flor   (the beautiful flower - such a beautiful flower)

Carlos llegó en su pequeño carro. -> I consider (and it's evident) Carlos' car is small.
La enorme casa dominaba el paisaje = The huge house towered above the landscape.

3. After the noun -> To distinguish the subject from the others of the same kind. The phrase "La rosa hermosa" may imply that there is another rose, but not so beautiful one.
Carlos llegó en su carro pequeño. -> Carlos must have another car bigger than that one.
La casa enorme dominaba el paisaje = The huge house (not the other houses) towered above the landscape.

4. Bueno 

Me he comprado un buen coche (I think it's a good car/it's the car I needed)
Me he comprado un coche bueno (it's an expensive, top of the range car)

Mis buenos amigos -> Those that really are good friends to me.

Mis amigos buenos -> Those friends of mine that are good people.
