I can recommend this apartment to everyone. I stayed here for almost one month and like a lot my experience. This apartment has everything for comfort stay: separated bedroom, good shower, big TV, well-working heating. It was very warm inside (I had problems with that in my other appts in Istanbul)
The location is amazing, it’s on the calm street but only 5mins from Taksim square / İstiklal street. Galataport is also very near. But be ready that this district has many hills and you should go up and down each time.
The host was very welcoming and helpful.
