Hi Susan,
Hopefully this will get you within 20 yards of Cafe Rose, Get to the main road from the Tansas, that leads to Deniz Kapsi, and Dolmus terminus. This road will go over the "Dry" canal as it passes Cafe Anne. At Cafe Anne where the road goes over the Canal, turn off the Main road and head towards the back of Icmeler, with the Canal on your RIGHT, the road will split into three. take the Centre road, Cafe Rose is a few yards up this road on the right as you go up this road,,,,the entrance looks a little like an over grown garden.
Hope you find it, unfortunatley I have only passed and not eaten there yet...
Steve
