The flat is super nice, modern, clean and very enlightened. Irem was very kind and let us leave our luggage into the flat before the check-in. Very big shower, shampoo and bath products were available, which is very kind and not obvious. The area is quiet and there's no noise issue during the night even though the place is definitely central. The location is strategic: 3 minutes by walking to clubs, bars and restaurants in Beyoglu, 4 minutes to Ikstal Caddesi, 15 minutes by walking to Karaköy, 10 minutes by walking to Galata Tower... Simply great!
I absolutely recommend this place!
