we were warmly greeted by Hakan Mustafa' son. he helped us with the luggage and explaining everything we needed. He also helped us in receiving our missing luggage by providing his details as a contact and receiving it while we are outside.
The apartment is in excellent location near Taxim square and 50 metres away form Istiklal street. the apartment was clean very spacious and has anything you need. the only drawback is the loud music from discos downstairs particularly on Thursday, Friday and Saturday. overall I would recommend this to everyone unless you are a very sensitive to loud music.
