This trip was centred on a trip to visit our son who is in Ankara. I decided that this was an opportunity to visit Istanbul. Via Evaneos I made contact with Demavend travel (Mehmet) who booked our hotel in Istanbul, arranged transfers (airport to city; city to rail station), two days with a guide (Ms Pelin) and onward travel to Ankara by train. We arrived on Monday evening, had two days of guided tour, one day free and then one day of travel to Ankara by train (Friday). We flew home from Ankara on Wed. Istanbul was the tourist city, Ankara less so though it has a very good museum of early civilisation (amongst others).
