I stayed in Mücahit's place for one month. The place had all I needed for living and it almost felt like a private appartment.
On the first day Mücahit showed me places around (food places and suprtmarkes) and took me to a tea house. If you want to try an actual good Turkish tea - highliy recommended.
Mücahit speaks English well for basic communication, though Translate app was helpful for more casual talks.
The room was clean and larger than it may look on the photos. Comfortable even for 2 people.
The location is in a very quiet area with just enough shops and restaurants to not attract many people. A lot more shops and food places are just across the bridge near the university. A bus stop is minutes away from the apartment. That said, it may take 30-60 minutes to reach touristy parts of the city by public transport.
Mücahit is a very quiet person. I did not even always notice him coming in and out the appartment.
