we had a wonderful time in istanbul also thanx to a clean room to sleep in and a wonderful view at breakfast. the staff was always very kind and helpful and i liked the freshly baked pastry for breakfast.
the construction next door didn't really matter either as we were only in our room to sleep or a quick stopp inbetween.
the hotel is located in a quiet area and eventhough our room was facing the street, it was easy to sleep well!
