The location is really awesome. It's right off of Taksim Square metro/bus area, and it's a fun location where tons of shops and cafes are around. The flat was clean, the bed was comfortable, and the washing machine was a plus. Garen was also friendly and gave us some good info on how to get there from the airport (there's a shuttle for 10TL). He also provided us with some laundry detergent, toilet paper, and fruits in the mini fridge.

The onl thing I'd add as a negative note is that although it says it accommodates 4, the flat can only accommodate 3. The double bed fits two, and the couch/bed in the living room really is only big enough for one person comfortably. Maybe if you're doing a one night stay and dont' mind squeezing in, 4 could fit. But otherwise, it's a stretch to say the flat can sleep 4 people.
