The apartment was excellent. Couldn't recommend it (and Emre) high enough. Just a five-minute walk from Taksim Square (metro station and bus transfers from/to airports). Fresh, clean. Amazingly quiet even though it's just literally a two-minute walk from a busy shopping street. Emre's guidance and advice was the best I've ever had. If I'm ever in Istanbul again, I'll be sure to check out the availability of this apartment.
