Commendations:
My stay at this place was satisfactory. I never met Melike, but her property managers Mustafa and Ali instead. These two men are great, despite them knowing little English, they were incredibly helpful and gave me a quick tour of the surrounding areas to the flat for the ATM, grocery store etc. Initially, I was unsure about safety, but reflecting on it afterwards, I felt totally safe at all times in the area. You will run into other tourists here too. This is in one of the best locations in my opinion, as Sultan Ahmet area, with the Blue Mosque and Hagia Sophia both within a 10 minute walk. Other more central parts to Istanbul are far too congested. You have to keep in mind that this is an economical/affordable AirBnB, so don't have stratospheric expectations, but does the price per night live up to the value? Absolutely it does. Lastly, the bed is very comfortable and the A/C works great.
Suggestions/limitations:
One thing that would have been nice is having a photo of the bathroom. The facilities work great, but I was curious prior to booking my trip. The toilet is at the end of the bathroom where the shower is at the front. So if you shower, it will be wet should you want to access the toilet.
Highlights:
The best part were Mustafa and Ali. These guys made sure I had a comfortable stay and did whatever they could to make sure I got what I needed as they were just a WhatsApp message away. I totally recommend staying here to experience Istanbul on a budget.
