Mehmet is a very helpful host who is quick to reply to all sorts of questions before and during the stay. With my flight arriving at 6:40 am, he kindly let me check-in early, which I greatly appreciated. The self-operated key box check-in was very smooth. (I wish all Airbnb host uses this!)
The apartment is conveniently located in the Galata tower area with Migros (small supermarket) and the public transportation nearby, in addition to cafes and shops (they are geared towards tourists). Although it could be touristy and crowded, the apartment itself was surprisingly quiet.
The apartment is on the third floor of a historical building. It has no elevator but it was not an issue for me. The bedroom/living area was beautifully decorated with the ornate ceiling. The kitchen had all the supplies and tools necessary for "real" cooking.
Overall, I really enjoyed staying at Mehmet's place and would consider coming back. Strongly recommend.
