Necati is a great host - he is very friendly, helpful, welcoming and flexible.
The location of the apartment is great. It is really close to the biggest landmarks such as Hagia Sofia or Blue Mosque in Sultan Ahmet district.
The apartment itself was neat and clean. It wasn't 100% as per the photos since in the photos I could see 3 beds - 1 queen bed and 2 single beds but in the apartment it was 1 queen bed, 1 single bed, and 1 single mattress on the floor. But the apartment has almost everything one mostly needs during their trip.
One thing to surely consider is the approach to the apartment. Our apartment was on 3rd floor (considering ground floor as floor zero) and since there is no elevator, it can become a bit difficult for elderly people or children to climb up or down all those big stairs.
Overall, considering the price of the apartment per night which was cheaper than the most in this great neighborhood, one can fairly say that this apartment offers good value for your money!
