We were a group of 4 remote workers enjoying Istanbul for the first time and we couldn't chose a better place. Hisham's apartment is wonderful, comfy beds and just as described in the pictures, also the terrace is amazing and the sunsets are breathtaking.
Note that the apartment is in a hill, so getting there without a car is a bit challenging, but overall is worth it. You have a convienence store just across the street and a mall in just 5 minutes, the metro is around 15 minute walk and you can cross to Europe either metro or ferry.
The only thing we had trouble was the internet, since we work remote it we needed to have good connection and it stoped working the last two days. But since it is an easy fix it didn't affect my review for the place.
The communication with the host was perfect and fast, also he helped us arrange a taxi to the airport on our last day and it was super comfortable and for a great price! Don't hesitate to ask him about this :)
Will stay again, 100% recommended!
