We went to explore the most famous market of Istanbul - Grand Bazaar. The best time to visit this market is in the morning when it is least crowded, so try to reach here by 9-10 in the morning. Frankly, this market was very average and they sell very low quality stuff. I will prefer Taksim market any day.
We went to explore Blue Mosque and Hagia Sophia.
We went for the Turkish Bath(must try), there are a lot options available in Istanbul. Contact your hostel/hotel for nearest and best option available.
After chilling for sometime at Taksim we headed to the bus stand to board our bus to Bodrum.
