My brother and sister and I had a lovely stay at Doret's apartment in Istabnul. Her brother Izel coordinated shuttles for us from the airport and met us at the apartment. He gave us a map, suggestions for our stay, and made sure we had a good sense of the neighborhood before leaving us. The apartment itself is very comfortable with air conditioning and everything you need. It is very centrally located, too. I would absolutely recommend this apartment to friends and family traveling to Istanbul.
