You can look on the school's website to learn more about the school. Some aspects about the school that you could mention is the fact that mcphs is the largest pharmacy school (therefore a large alumni base which will be beneficial), the school is conveniently located in the longwood medical center - across from Harvard medical and dental school and adjacent to many prominent hospitals, the city of boston is very diverse and so is the school, and such. It's not enough to simply mention these points; it's more important to use these points as explanation of why you (as an individual) chose this school.
hope this helps!
