The place is perfect in each sense.
Check-in was smooth though I was more than 2 hours late, the host was understandable.
As a person who travels and works remotely, it has all the amenities I need for a comfortable stay (and btw it looks cool!). The flat is located on a noisy street but I've never had any issues with that. Thus, you have a walking distance access to all the bars and restaurants in the district.
And most importantly, the host is outstandingly nice and always responded to my requests in like a minute or two.
With all that said, I highly recommend this place for Istanbul visitors!
