The Apt is pretty much as described. It's clean, cosy, you can have a nice time during your stay in Kadiköy, it's very well located, the communication with Demir is excellent, check-in and out works very well even without meeting someone. So actually it should be a 5* ranking. Here come the 'but':
You share the terrace with your neighbours. Those people are sitting literally with you in your living- and bedroom. There is no privacy going to the bathroom or even going to bed.
It has been said that there is a closing hour of the terrace at 9pm during the week and 10:30pm on the weekend. I had to kick off people from the terrace every night at 11pm or later. Every night ! Thats quite annoying especially when they start to argue with you. Demir posted the Terraces rules (closing hours) at the door, but without attention to anyone. There should be a careholder who is responsible to lock the door. That did not work at all. Nevertheless I even found a paper in the hallway with closing hours of the terrace announced later than midnight every day... so I don't know what to say.
Demir is trying his best to run the apt smoothly for his guests, but that terrace issue should really be solved accordingly. That's why I did a 3* ranking only.
