I lived in this apartment for two weeks. A wonderful apartment that has literally everything you need and even more: interesting books (really good selection of books on cooking and travel), TV with netflix and excellent stable internet connection.
Good location on a quiet street close to various Sisli restaurants and cafes, bus and metro stations. Couple of markets and a trade center are easily accessible by foot.
The apartment is located on the ground floor and this is perhaps the only thing that can create some discomfort: I worked remotely every day and I missed sunlight a bit.
Apart from this, this is a very pleasant and comfortable accommodation, and Gizem is a super host who is not only always in touch on any questions, but also a great person to talk to.
P. S. Oh, and the bed and pillows. I slept really well :)
