The apartment has a number of outstanding benefits for those who would like to explore Istanbul on their first visit. The location is great, very close to the main tourist attractions like Galata Tower, Istiklal, Galata Port, also very close to all possible transport means like metro, tram, bus, ferry. Many good restaurants (incl. the best Falafel ever) are within the walking reach from the apartment.
The Internet connection was very decent, at around 30 mbits.
Cihan was very kind and helpful to us. The check-in and the check-out were very smooth and convenient for us.
On the cons side, be ready that the apartment is located in the historical part of the city, so be ready for high humidity, lack of elevators, and mountain-like landscape nearby.
