The apartment is great honestly and I absolutely loved staying there.
It's a minute walk from Taksim. There's so many grocery shops, cafés and restaurants nearby. The communication with the hosts was great and literally anything I needed was done in less than 24 hours! This was easily my best airbnb experience ever. I'd book this place again in a heartbeat :)
Note: The place is on the top floor right beneath the roof so you can hear cracks and other noises from birds. If you're sensitive to sound and a light sleeper (like me), don't be scared the first night you hear it, it's literally just the birds.
