Racism is absolutely present in Izmir and Turkey. You only have to take a look here https://en.wikipedia.org/wiki/Racism_in_Turkey to find systemic racism "towards non-Turkish ethnic minorities such as Armenians, Assyrians, Greeks, Kurds, Jews, Yazidis and Zazas as well as hostility towards minority forms of Islam such as Alevis, Sufis, and Shiites."
It's a beautiful small city with nice parks. The population is somewhat used to foreigners since there are many humanitarian agencies with offices in the city. Nevertheless, basically no one speaks English. There is a large mall with several options to eat and work. I've spent days in local cafes without issue although cafe owners were clearly surprised by this behaviour. Regarding activities, they are constrained to the touristic, such as museums, and hamams (saunas). I've heard that there are pubs and places to dance but I've not seen them. The female population mostly behaves as small town people. Caring about appearances and stuff like that. Be extremely careful with traffic! No rules are respected. Finally, this nation has an honor culture, like all of the region. Do no criticize anyone for anything!
