Compact but very comfortable, and fully equipped apartment. Great location in the center of Kadikoy district. A lot of cafes, bars, stores of all kinds in the near vicinity. Outside is noisy at nights, but you can barely hear any noise inside the apartment, especially if the AC is turned on, so it wasn't a problem for me.
Apartment has a comfortable place for working. Internet speed is average, not very fast, but still decent.
Host was great too - very polite and quick to answer and help with any question I had.
Overall, it's a great value for the cost! I would definitely recommend.
