Oytun's place is really close to Taksim square, easy to get the Havabus to the airport and the square has many restaurants and shops, and great transport links. This place is a hotel and so you get the added bonus of daily cleaning, and little touches, like a couple of bottles of water each day, and check-in and out anytime day or night. Only downside is the room doesn't have power without the room key, meaning there is no way to keep food good in the fridge if you're out throughout the day. Traffic is noisy but that's the price you pay for such a location and at such good value, I would recommend using Oytun's place.
