This is a fantastically located central spot if you are visiting Istanbul for the first time - it is walkable (20-30 min) to Karikoy/Eminonou where the main tourist attractions are, but it is outside the chaos of the main tourist spots for more quiet. Istanbul is a huge city and we walked everywhere from this place.
The view is unbelievable, especially at sunset and night when the entire city is lit up. Beware this is a 6th floor walkup, so if you are traveling with older guests, young children, or with heavy suitcases, perhaps consider requesting a unit on a lower floor - we definitely got our workout in staying here for 6 days.
Thank you for a great stay!
