Great place! very convenient, spacious and modern apartment. Unlike many other apartments in in Istanbul that I've seen, this one looked exactly like on pictures. The location was perfect to us (my wife, 2yo daughter and myself) - we did not plan any sightseeing, we simply wanted to spend some time in a beautiful place next to the see. In 5-min walking distance you can find: dozens of cafes / restaurants / bars, one (out of 3 in Istanbul) kids cafe, best embankment in Istanbul, super-busy Bagdat street, minimarkets etc. The area is rather posh.
The host is a very nice and polite person, fluent in English, helpful and always available in whats-app. Checking in and out was smooth and right on time.
Thank you so much, Gokhan!
