Our galaxy's black hole corresponds to the location of Sagittarius A. A black hole's size depends on the size of the star that it starts from, and will grow with time.
Since Andromeda has a much larger bulge than the Milky Way's, then it is able to have more black holes. The bigger the galaxy the more black holes it will have.
Where is the black hole in our galaxy, and why does the black hole start out small?
