Ok so I was a little worried because I saw one or two reviews but LET ME TELL YOU, this apartment was great! The rooms were spacious, AC worked (a little too well lol), enough towels, clean, and very comfortable. Also the host was so accommodating and polite, he answered all our questions and concerns (and we definitely had many)!
As for location, this apartment is perfect, we were within walking distance to all the coveted attractions of Istanbul, and I must mention a quaint rooftop restaurant on the same block called "My Terrace" with a great owner and service and unbelievable view.
Another touch that made our stay a lot better was the transfer from and back to the airport, there were no problem or trouble like i read in some reviews. It was air conditioned, spacious, safe, and smooth. Thank you to Ali and Ramadan for this nice stay.
