My two friends and I stayed at Isik's apartment in the third week of May. The apartment is at a great location - a few hundred metres away from Taksim Square and the funicular and also walking distance from Istiklal Caddesi. Isik picked us up at the bus stop late at night and also helped carry our luggage to the apartment. We used Isik's phone at a very nominal cost and he also provided us with the Istanbulkart which proved to be extremely useful. The apartment was neat, clean and had all the basics in place including a good wifi connection. Isik is a great host and was always available on phone to respond to any queries that we had. I'll definitely rent one of Isik's apartments again on my next visit to Istanbul and would recommend it to anyone travelling to Istanbul.
