We stayed in Ali's place for a family reunion. You cannot beat the location - it is about 5 minutes walk from the blue mosque/aya sofia area and very close to grocery stores, restaurants, and shops. Even though its in the middle of the touristy area, the apartment is in a super quiet street - so you don't hear any street noise. Ali went above and beyond to make our stay comfortable - he arranged transport from the airport, met us at our apartment and gave us tips, and promptly answered my numerous questions over whatsapp. We had our 1yr old daughter with us - so the crib and high chair in the apartment was very handy.
