This place is a great value! My fiancée and I stayed here for 5 nights in June. It does have AC which we used on some hot nights and afternoons. It’s a quick light rail ride across the river to all the historic Old Town sights, but very quite at night and close to Galata Tower and one of the main shopping drags. There are also a number of casual restaurants close by, and it’s a short 15 min walk to some nicer restaurant in Taksim as well.
