We had a delightful stay at Talyan's apartment in Beyoglu. Great location, easy access to the best restaurants and bars in town and good public transport links. Loved the decor, hot showers (even when 5 people had showers each morning), comfy beds and the rooftop view of the Bosphoros and the Golden Horn is amazing, we sat up there sipping tea most evenings. Kitchen was well equipped, although I must confess we didn't use it, there were too many fabulous places to eat and we didn't want to miss out.
Talyan was a most excellent host, he did everything he could to accommodate our early check in requests and stored our luggage for a few hours when we checked out. He was always available to answer my questions and was so helpful. Can't recommend this place highly enough.
