enRoute by Air Canada has mentioned Unison Turkey on the latest issue. We present kindly thanks to enRoute… “Enlist a tour guide, like Unison Turkey, to show you around the oldest area of Istanbul. Don’t miss the 1,500-year-old Hagia Sophia, which was originally built as a basilica and spent time as a mosque before it was transformed into a museum. The nearly destroyed mosaics are as impressive as the structure’s enormous domes, making the site a masterpiece of Byzantine architecture. The sprawling Topkapi Palace and the Blue Mosque are within walking distance of the Hagia Sophia. http://unisonturkey.com/“ – enRoute / Air Canada http://enroute.aircanada.com/en/destinations/istanbul-2/activities/tour-old-city
