If you go on the Gunlukbasi Road from Calis, keep to the right just before the Police Statiion (the Pollice station is on the opposite side) there is a small lane with a Turkcell shop on one side and a Bakery on the other. Just turn down this lane on the right, the glass shop is next to a Barbers. We were they today as there is a key cutting shop next to the Glass Shop.
