Sisli District; is Congress Tourism, Congress and Centers Hotels and Centers of Istanbul, European side of the city.
Now that the wealthy elite of central Sisli have moved further out of the city, the large buildings on the grand avenues are occupied by offices, banks, and big shops. Since the 1970's most older buildings have been pulled down and replaced with newer, and perhaps less remarkable, multistory structures. The back streets are still residential, and many working-class families and students have settled here. As in most parts of Istanbul, the number of people living and working in these blocks challenges the existing infrastructure; for example, competition for parking spaces is intense, and traffic during peak hours can come to a standstill. But for the residents of Sisli, there are plenty of shops, cafés, pubs, and other amenities and these make life in Sisli still manageable. Additionally, Sisli's central location to other important areas of Istanbul adds to its desirability.
Being a central area well-served with public-transport and other infrastructure, Sisli is a center of trade and shopping. The main road through Sisli up to the skyscrapers of Mecidiyekoy, Gayrettepe, Levent and beyond is now lined with office blocks. Europe's largest and the world's second largest (urban-area) shopping mall, Cevahir Ýstanbul, is situated here. Due to Sisli's middle-class past and the enduring quality of some neighbourhoods the area is home to many upmarket shops mainly in the stylish and charming Nisantasi area. Parking is an enduring problem, especially in the narrow side-streets.
Education
People also come to Sisli for schooling; this city center area has some well-known high schools and a great number of courses for the annual university entrance exams, evening and weekend schools where people come to cram for university or high school entrance examinations, or to learn English.
