We had a wonderful time at Idil's apartment. Lots of beds (can easily accommodate 6), properly stocked kitchen, two toilets and best of all: it's a stone throw's away from Galata Tower. It's very nice to be located there, because you're very close to Istiklal (where all the action is), but you're not next to all the clubs. You are in the old center, so you might get woken up by the call the prayer at 5AM, but that's a small price to pay for the location. Idil was very fast and responsive in responding to our questions.
