The apartment is really neat and organized. We felt like we were actually living in a real home. The large couple's bed was great and comfortable, the bathroom had everything (from the washing machine's products to towels and shampoos) we needed and the photos are not enough to show how fantastic the viewing from the balcony is. There are two common markets (Sok and A101) really close to the house and one of them even sells Istanbulkart - which you'll certainly need. Although far from the city center, you can take a couple of buses to it and the neighborhood is really calm and peaceful.
Also, from the beginning, Ugur was REALLY helpful and answered kindly all my questions about everything I asked.
