I stayed in Hamza's place for a full month. I work online and the flat had everything I needed to be productive. It has comfortable furniture and great WiFi. So if you're looking for a good workspace to supplement your exploration of Istanbul this is the place. Getting out is easy. The neighborhood is wonderful. There are restaurants and cafes on many of the single-lane streets. You'll find the metro, Mamaray (the train that goes under the Bosphorus), and my favorite, the ferry, all within easy walking distance.
There are two simit bakeries nearby. One is directly across the street. If you don't know what a simit is you will soon after you book the flat. They're everywhere. Look it up.
