First of all I want to say that Sinan is awesome! He is ready to help with everything, he allowed us to stay til the evening at the checkout day, he helped us with the bags on the checkin, he tried to arrange a taxi minivan for us. Really, Sinan is awesome! Thank you!
Apartment is cool as well! The coolest thing is obviously a terrace! Actually, there are two terraces, but the open one is the best. There is a hanging chair where you can literally curl up and have a nap or sunbathe. It is the last floor, so you really feel like on the top of the world. There is a mosque right in front of the terrace so you can admire muezzin's vocal and beautiful lighting on the mosque at the evening.
The living room is nice and stylish - it's really a pleasure to chill there. Also there is huge TV with youtube/netflix, good sound system, playstation if you are bored :)
The apartment is pet-friendly and we stayed for 18 days with two cats. The cats were also happy - there are many places for them to chill and, of course, they liked to sleep on the sun on the terrace.
The only thing I will note is that the bedroom is a little noisy if you sleep with the windows open, since the window faces the street. But it's not loud music from the bar or any similar sounds, it's just the sound of passing cars. It didn't bother us much, but if you're a light sleeper, bring earplugs.
