The location of the apartment is great - right in the heart of the posh and beautiful neighborhood of Arnavutkoy, surrounded by excellent eateries, and one minute walk to the Bosphorus where you can take a stroll or run. I didn't meet Adem but he was very responsive on whatsapp. He kindly let me check in a bit earlier and on the checkout day he let me leave my suitcase in the apartment until my evening flight. As other reviewers have mentioned, you need to climb two floors of narrow spiral stairs to access the apartment, so it is not ideal if you have heavy luggage or have mobility issues. Overall, Adem's place was a good value for money.
