The most cozy and homely stay in my experience.
An apartment is very bright, clean and thoughtfully designed: everything is very comfy (the bed and the sofa) and everything you may need is at hand (all the kitchen supplies and sleeping and bathing necessities). The living room area and wi-fi were perfect for working remotely and even doing Youtube workouts. The apartment is situated perfectly — so you're always have loads of light and the sun in one room and you can rest in the shade in another.
The area and location are also awesome — very close to Taksim square and metro station, but without the hassle of the above mentioned. The street and neighborhood are very residential and quiet. And 10 minutes by foot to a lovely Cihangir and Kabatas ferry station. Also Maçka Park is very close, which is one of the few places in Beyoglu for running or jogging.
Merve is an amazing host, very kind and helpful, сommunication went smoothly. Meeting her was like meeting an old friend.
I would definitely recommend my stay. In fact, i liked it so much, so i even asked Merve to prolong my initial 1-week stay for a second week :)
