To anyone who is reading I would say that you should know few things before booking this place. First, for tourists this place isn’t comfortable. It is better to book in Sultanahmet or Taksim as you will be near to many historical sites and transport is much more easier over there.
Second, I didn’t feel safe! Although Hilal was a nice and helpful host, it is not a place that you would go late in night. It is a bit isolated and as a tourist this is the last thing you want!
Third, the apartment overall is old. From the building to the room to the toilet everything seemed old. Also, cleanliness was mediocre!
Overall, I wouldn’t recommend this place, especially if you are a tourist in Istanbul!
