From Ishikawacho Station go out the main exit and turn right. Go straight and you'll see a big intersection with the Motomachi Bird Archway in front of you.
Cross the street towards the bird, but don't go down Motomachi, take a right, and walk (past IDA) watch shop until you reach the next street, Naka dori. There is a clothes shop named "Jewel" on the corner.
Take a left onto Naka dori and walk a few seconds until you see a large grey concrete building on your right. You will see Ceres Estate on the corner of the building. Walk up the driveway with Ceres on your left, and you will see a door on your left. Go in and take the elevator to the fourth floor. From the elevator go left and continue to the end of the hall.
