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!
Spent six months in Istanbul in 1993 when Turkey was really exotic. Didn't return till 2007, when I made mostly Kurdish friends in Sultanahmet, whom I'd see on frequent visits thereafter. Otherwise, I'd skip the city as like throughout Turkey bar the Kurdish areas there's anti Western feeling and targeting of visitors (I noticed that after a meal with alcohol, I'd nearly always be approached by a single male in the street near the restaurant inviting me to a bar certain. I'd suggest going to the first busy café instead, at which point they'd excuse themselves. I suspect some waiters were part of a scam targeting single males).
