Istanbul is a great city and we had a great time. Keirans flat was a perfect homebase - location-wise especially. It´s not as fancy as the pictures suggest, but it´s nice enough and a great place to stay for a few days. There are a lot of cafés, bars and shops near by and it´s only a short walk to the next Tram-station or the Galata-Tower. Perfect starting point for exploring this amazing city!!
