I had a very mixed experience. I will try to be specific. Sadaf and his mother are very accommodating and helpful, I arrived very late to check in and left very early to check out, it was no problem. Don't let yourself be impressed by the neighborhood, the building is very old and the streets not very well lit but we are safe. And then you just have to walk a few dozen meters to find yourself on very busy and animated streets. Moreover we are at approximately 15 minutes with feet of Taksim square. The apartment is equipped with everything we need for our stay.The only problem I had, and not the least, was the bed. I found it very uncomfortable. It was impossible to spend a full and restful night on it. On the second to last day, I even found what I thought was a bed bug, but Sadaf assured me that it was probably an insect that came in through the balcony. But I still wanted to check the mattress and I turned it over. That's when I realized that the box spring was completely broken, which explains why it was so uncomfortable.
To sum up, only book after you make sure that the bed has been repaired or changed.
