The location and check-in of the flat are perfect for a stay in Istanbul, as it is close to metro, Istiklal and even Sultan Ahmed district can be reached via a nice stroll. Also the facilities in the flat are perfect for someone who wants to spend his day exploring the city. The only problem we had were the really thin walls. You hear every step from the apartment above you and the school playground right next to the building. Also the house door will wake you up in the night if you have a light sleep. I would advise to bring some earplugs if you are not a super heavy sleeper.
