Even though our plane was coming late, and was even later than expected, Hakan welcomed us greatly at a late time, he was very nice with us!
He replied very quickly to the questions we had via Whatsapp.

The apartment on itself was big! The living room was great, very decorated, we loved it ! The view was also stunning, on the New Mosquee on the other side of the Bosphorus.
The room also was very fine.
The apartment was silent and clean.
Its well secured.
Wifi works well.
The only drawback we had is that the room smelled a bit cigarette.

Otherwise, the situation is very good. 5 minutes by walk from Istiklal Caddesi, 10 minutes from Tophane tramway, which leads directly to Sultanahmet.

Very good overall, thank you Cihan ;-)
