Orcun is a great host, very helpful and welcoming.
The apartment is in an up-hill or down-hill location depending on which direction you're coming from, that's just how Istanbul is. The neighborhood is great, there is a pet friendly park, a couple of stores 1 minute away from the apartment as well as some food and beverage places nearby. Slight issue with noise coming from the street during the night hence i would recommend earbuds.
