We had a wonderful time in Garen's apartment, which is lovely, very well equipped and situated perfectly, very close to Taksim square in a vivid and colourful neighbourhood. You find plenty of bars, restaurants shops etc. around the corner.
Garen is a very friendly and helpful host. Even the fridge was full and we had a big bowl of fresh fruit on the table. Internet was working very well. Just don't expect a great view. But we didn't need it as there is so much to discover when you step outside. And the prize is great as well :)
