I´ve been to Izmir for the summer holidays

Izmir is a beautiful place (no need for very, it´s already implied in beautiful, or else you could say it´s very nice)

Especially its sea and department stores are fabulous. I think the best place in Izmir is Bornova, both its ambience and its girls.

Sausryqua, could you have a look at my suggestions and tell me whether you agree or not? And 'hem kent guzel' means both the city is nice, where did you get 'ambience' from?

ok. i've revised it.
