The owner and the apartment itself are very nice. The apartment is small, for 1-2 people, but there is everything you need. The apartment is very clean. Internet speed 22 Mbps. The Internet was stable, but the last 2 days there were problems from the Internet provider, the owner quickly responded to all my messages and tried to solve the problems as quickly as possible.
There were four minuses for me (but it was relevant only at my time being there): 2 floors below were being renovated with the sounds of a sledgehammer, drills, hammers, etc. There was no internet for 2 days, there was no electricity for 1 day, if it was less than 18 degrees outside, it started to get very cold in the apartment. The windows face the courtyard of the building, they only see the roof and walls of neighboring buildings (but this did not bother me, there was enough light from the sun, but direct rays did not fall into the apartment).
The location is great, it's right in the center of kadikoy. The street itself is noisy, but as I wrote above, the location of the windows is such that if you close them, you can hardly hear the street noise (it didn’t bother you at all).
The owner is very nice.
