The Montessori method is great for kids who are good at staying in control of themselves and focusing on single tasks. It is great for helping to instill independence in a child, as well as often good for self-esteem. Small motor and thinking skills are especially emphasized.
However, children learn best through play and the Montessori method does not offer a chance for dramatic play - playing house, doctor, fire fighter, school etc - where children learn much of the dialogue and problem solving skills they will use for the rest of their lives. They are also not offered as many free play options as in typical preschools that are necessary for physical growth and development. Lastly, many children are not ready for the structure of the Montessori environment, they are geared for more physical, active, messy, loud, and large group activities.
If you are looking at Montessori schools, make sure they are TRUE Montessori if that is what you decide will work best for your child. Make sure your child is ready for and happy in that environment (many children do thrive there), and lastly be very aware of the teacher and their style - it is truly that man or woman that affects the child's day, attitude about school, and self-esteem which will in turn affect your families' nights and days as well. Personally, I would look into the method only after the age of 4 for most kids.
