I stayed 8 nights in Taner and Nicolas apartment with 3 of my friends, our stay was so comfortable. Communication with the hosts is 10/10 you can ask them for and about everything.
Check in and out is super flexible and easy.
The apartment is as it looks in the image there is a bakery and shops near it , if you’re interested to stay near taksim and istiklal street it’s the perfect apartment to stay in.
