Great small hotel, very close to Taksim square (less than ten minutes walking with a suitcase), hosts are very friendly and helped us out and even called a cab when we were leaving. Which was great, since the driver did not speak English and communicating would have been hard otherwise.

It is noisy but don't blame the hotel on it. This part of Istanbul is noisy and crowded in general so if you are looking for a quieter place look elsewhere.
