We stayed in Ozde and Omer's place for 3 nights as a family of 6. This place is at a great location, few minutes walking distance to Taksim square and very close to public transport. The flat is very clean, spacious, and quiet at nights. Ozde and Omer were very kind and responsive, they arranged a comfortable shuttle from the Istanbul airport for us, which I highly recommend taking instead of taxi or public transport. The place is at the third floor, be prepared that it is in an old building without an elevator. The flat has two floors, a lower floor with three rooms, kitchen, full bathroom and a small living room; and a second floor in the terrace that has a half bathroom and another brick-walled room. We were very happy with our staying at the lower floor but had issues with the upper level. The kitchen in the lower (main) floor has all the amenities for cooking or making tea/coffee, which we used it when we were staying there. Bathroom was nice and clean, rooms were also clean and spacious. At the upper level, the terrace has a nice view and a swing set that we sat every night as a family. Second bathroom in the terrace is a half bathroom, it has a shower head above the toilet and the sink is outside in the terrace area. So you have to go outside to the terrace to take shower or brush your teeth. We were also unhappy with the room in that floor, which had a musty smell and lack of air ventilation, I don't recommend staying overnight in the second floor. Overall, we enjoyed Ozde and Omer's place and had a great time in Istanbul, I just recommend to read through my comments and have accurate expectations before you stay there as a big group.
