We've stayed a week at Cihan's place and everything went very well. Very responsive and great communication from Cihan. The check-in was easy and they could accommodate us although it was a very last minute booking.
The flat is very well equiped and feels cosy, everything is functional and the kitchen well furnished if you like to cook.
The place is very quiet although jut off from Essex Road and in the Angel / Islington neighbourhood, it has great connection with the city center (bus and tube stop very close).
Great place to stay, enjoy and explore further Islington and London.
