excellent location. fun themed nights each night where you can get food or drinks for free depending on the night. good showers--hot and good pressure (hey, that's important for some people). need key to get into your room, which is good for security, but no lockers in my room.
AMAZING location--right up street from the Cathedral. Clean and safe, too--great vibes!
Really charming place w/ very friendly staff. Difficult to find (we had to call them from a Turkish cell phone to pick us up at Galata Tower), and had to climb a steep hill every day to reach the main street, but still a really good atmosphere. Simple breakfasts each day with a nice view of the city. I felt safe in the hostel, but I'm not sure if I would recommend going here if I were a single female. The lock on our door always worked, but walking back at night might be a little sketchy.
