Follow the N7 to the start of Inichore. Where the Luas turns right at the canal, you turn right also. Follow the canal to Baggot street bridge (Maxol garage just before junction . ) and turn right. Straight then into Ballsbridge. If you are going to the clinic on Wellington road, then when you turn into Baggot street, continue past next set of lights and then its the next right.
Can somebody confirm that you can still make the 2 right turns above as its been a while since i have done this.
This is not the quickest route but its probably the most straight forward.
