Selim's apartment is located in a very good place near to Taksim Squar. It is convenient to take Metro to any place. Also a shuttle to IST airport.
The apartment has an elevator that big suitcase can be easy carried. Clear kitchen and bathroom, cosy bedroom. Even it is a little noisy because of the night clubs, it is still a good place to stay in Istanbul if you dont mind.
Mr. Selim gave me a lot of tips, and helped me to find an Eczane, many thanks.
