Honestly, I was worried because this was my first time visiting Istanbul and solo traveling. However, I got a great time staying at Enes' home. Enes and Can are nice guys and helped with everything I needed. Plus, I felt comfortable and safe, like I was at my home, although I was the only girl staying in the apartment.
The apartment is on the ground floor but cozy and fully equipped, and clean; all you need is to come with your luggage.
The location isn't in central, far away from the tourist area, but it doesn't matter because the bus station is just 200 meters far and you go everywhere by bus or Metrobus.
Last but not least, you can enjoy walking in the forest with Enes and Omar sometimes or make a picnic tour in good weather with them.
