This was a great place to stay for the price - gets good sunlight in the daytime and in a quiet street, max 20 minute walk from all the tourist sites in Fatih. It's on a quiet street in a cute neighborhood near the Little Hagia Sofia, and my two favorite places to eat, the Rabbit Hole Cafe and Ziya Baba Slow Food, which you should check out if you're in the area :)
The landlord is very attentive and responsive; I got help with any problem or confusion I had almost immediately.
The wifi was really spotty or slower than expected (and occasionally went out entirely). In Istanbul that's kind of a given, the wifi is bad everywhere, but this airbnb advertised fast speeds, which were not accurate in my case. (There was also no TV or soap as advertised but it wasn't a big deal for me)
