I stayed at Emrah's airbnb for 2 weeks and my experience was nothing shorter than perfect. Emrah was always so helpful and ready to assist me with any trouble I had. The room was super comfortable and it was easy to get to most places from there. It's not super close to the main touristy attractions but for me that was a plus, Beyoglu is much livelier and young than sultanahamed and I also felt safer walking around Beyoglu. There are so many cute vintage and antiques shops nearby, as well as anything you might come to need: the airbnb is 5 minutes away from groceries shops as 2 minutes away from the fish market, which has fruits, fish, sweets... Because of covid they also had separated kitchen utensils for each room, making it extra safe and he provided me with extra pans I needed as well! Basically, if you're looking for an amazing and helpful host and a really central, cute and comfortable flat this is the place to go!
