I had read the comments for the place and they are all correct:
Clean place, very comfortable place , good A/C for warm summer, basic appliances in the kitchen etc.
Need again to mention that Berk was very fast responsive and helpful. He booked us taxi from/to airport which we really appreciate it.
The location is so close to Taksim sqr. A little bit up hill, bit still manageable for my old mom to walk all the way to Taksim and istiklal street. There are plenty of small supermarket and fast food around as well.
The only “drawback” was that the immediate area is not that clean and fresh, which might be some how unpleasant walking “home”.
But generally it was a really good stay and with nice communication with the host. I recommend this place.
