I've stayed at Idil's place for 10 days and it was awesome. The bedroom and bathroom were very clean and there was hot water 24/7. I've used the kitchen once or twice and Idil provided me with all the utensils. A couple of times I had to do work remotely and the internet was very stable to had a solid connection the whole time. There are a few other people living in the apartment and they are very courteous and nice people, we even went out to clubs a couple of times. The apartment is also close to buses and ferries (to go to the asian side and Bosporus Tours), the tram is 1 stop away via bus.

Idil provided me Istanbulkart (refillable mass transit card) and that made it really easy to get around the city. Idil was very helpful with directions and places to visit and other things. If I ever go back to Istanbul I will be staying at Idil's place for sure. She is a wonderful :)
