The appartment is located close to the main shopping and nightlife street (İstiklal Caddesi), and is also in walking distance of the Galata tower. Perfect for visiting Istanbul. When you are fit, its easy to walk to the asian side. (highly recommended) The apparment looks like on the pictures on air bnb and was very new and clean. It appears to be a bit bigger in the pictures as it really is, but its fine.
As it is so close to a main street, on Friday and Saturday nights it is rather noisy during the night, due to the taxidrivers extra loud music and the party people talking and singing right in front of the appartment. If you dont mind that, its an awesome place. The showers (there are two) are very beautiful and confortable and everything is available (a strong hairdryer) good light and so on. I can recommend the place.
