Deniz and her partner made our stay comfortable and are available for any queries anytime of the day. If there are any issues they address them immediately.
In fact on our day of arrival, Deniz helped us with the luggage to the apartment.
Very sweet and attentive hosts. The location is great wherein all tourist places are reachable and within minutes by public transport. Really nice cafe's and restaurants around the apartment. You can blindly trust Deniz and Emrah's recommendation for Turkish restaurant's.
In short, "If I am in Istanbul again then apartment from Deniz would be my preference to stay".
