Demir’s place is very nice, clean and organized, it’s also close to a lot of local shops, cafes and restaurants and grocery stores (the area is really nice btw) and a mall called City’s Nisantasi, the subway station Osmanbey is around an 18 min walk which is not too far, the one thing Is when ordering an Uber or Taxi make sure to tell them the exact apartment number because a lot of them end up not finding your exact location + tell them to use the taximeter (general tip for Istanbul) other than that I definitely recommend this place :)
