Mahmud is an excellent and very helpful host. Even though he just got back from his holidays when we arrived, he was willing to show us around and to take time for us right away. Besides he organised a shuttle bus to take us from the airport right in front of the apartment for a fair price.
The apartment itself is very nice located close to the Blue Mosque and the Haiga Sophia Mosque. The rooms are spacious and the fact that every bedroom has a bathroom was very convenient. The apartment looked exactly like on the pictures.
In the neighbourhood you can find cafes, Hotels, restaurant places, shops, so a good mix of everything. It wasn't too noisy in the evenings nor too busy during the day.
