This apartment is WONDERFUL. I stayed here whilst moving between places in Istanbul and it was the perfect stop gap. It is cosy, but airy and the neighbourhood is excellent - easy walk for Istiklal, Karaköy, Galata, Asmali Mescit...
Izi was also unbelievably helpful, even when I was being flakey about dates etc...
I had a small issue when I arrived at 2am off a flight due to there not being any drinking water, but I messaged him and he responded immediately and I was all sorted (with a bar of chocolate too!) within 15 minutes.
Things don't always go to plan, but the key for me is how people react and sort a situation and Izi sorted it and then some!
I could wax lyrical for hours, but all I would say is, STAY HERE!
If I ever need a place again, I will!
