Once famous for figs, Izmir (formerly Smyrna), is now Turkey's 3rd-largest city, the "capital" of the Aegean region, a major port and commercial center set dramatically around a huge bay and backed by mountains to the south.
Today Izmir (EEZ-meer, pop. 3 million) is a mostly modern city with good hotels and restaurants, an interesting bazaar, a few small archeological sites, a big, busy Otogar, and an important airport south of the city on the way to Ephesus.
Some travelers use Izmir as a base to visit such regional sights as Bergama, Ephesus and Pamukkale, because Izmir has some of the best modern hotels in the region.
You needn't linger in Izmir if your time in Turkey is short, but if it suits your schedule to spend a night here, enjoy Izmir's Aegean ambience: see the sights, wander in the bazaar, sip drinks and dine at the pleasant waterfront restaurants.
While you are in the area make sure to visit Urla, Çeşme and Seferihisar which has lots of historcial sites nearby. The best view in Izmir watch the sun set at the top of the Kadifekale East of the city at 250m high top, over looking to Aegean sea. Also 20km west of Konak suqaure at Balçova, take a tour to the mountain by a cable railway and enjoy the view from the forest and eat lunch or dinner.
