I stayed here for ten-days and it was my "Home away from home."
Nevermind the great view (that never got old) where I enjoyed tea and fruits every morning, the great living space, nice TV, fully-stocked apartment and washer that really enabled me to have a great stay, but the layout of the apartment with a triple exposure meant the apartment was constantly airy/breezy.
Being a block off of Taksim Square meant all transportation was great, whether using the metro system to go to Sultanahmet, catching cabs to Nişantaşı, or even just an easy walk down to the Bosphorous and Karaköy, but Cihangir itself was at the doorstep and had more restaurants, bars, shopping, galleries and cafes than I could manage to try!
Most of all Efe & Memet were very responsive, so if anything arose, they would be there to help, including helping me with my luggage upon check in and checking out.
