Despite arriving incredibly late, Isik was more than accommodating and met us happily to show us the apartment. The location was fantastic-- right off Taksim and yet quiet. He communicated with us throughout the weekend, making sure we had everything we need without being intrusive. He also made plans for us to store our bags for our late departure from Istanbul so that we didn't need to carry them with us. The apartment itself is well stocked (including drinking water!) and adorable, with good wifi.
