We stayed for 1 month and decided to stay longer. The apartment is great, the location is perfect, and the best is the host, Kaya, who is a very good host, answers questions quickly, and is always ready to help.
The apartment is great for longer stays, and it has everything needed. Kadiköy is the perfect balance between local life, cool/hipster cafes and restaurants, and a very nice energy.
I recommend this place wholeheartedly.
