Great apartment with great location. If you want to stay in Kadikoy then this neighbourhood is perfect for it.
The apartment has everything (well, except for a shower curtain and an AC), right down to a toaster (microwave, electric kettle, washing machine, etc.), the bed is large and comfortable, and there is a large table if you're planning to work. The windows face two opposite sides of the building, so the apartment is well ventilated.
Overall experience is definitely positive, so I would recommend this apartment.
