Dublin has a range of cheap English schools
and the cost of life here is one of the cheapest comparing with London, Australia or others destinies that exchange students might choose.
I would redo that boldened bit. Not to be misunderstood as "cheap" in the sense of "inexpensive because of inferior quality".
So, perhaps you find it interesting to change it into "Dublin has a range of cheap, yet reliable schools" or "Dublin has a range of reliable, cheap schools." etc.
Just to soft the "cheap" statement.
It´s me, though, others may think otherwise. There is the context afterwards, it compares the Dublin living expenses with that of London, Australia.
