Location is ideal if this is your first visit to Istanbul, touristic but in the middle of all attractions with plenty of cafés, restaurants and bars around. Host was prompt, and answered all questions. One thing that stands out is how spacious the apartment is with its two balconies.
Yes the area is busy, but luckily the apartment is just off the noise and the crowd. You will quite enjoy musical insturments playing in the background every morning apparently from a nearby music school.
What you need to be aware of, taxis and Uber will keep refusing your order due to traffic to get to the area unless you pay them double/ triple the taxi fare. Going up three floors of steep stairs was a bit uncomfortable with the luggage and after coming back to the apartment following extensive walks around the city. We also had no water almost the entire daytime upon arrival but host answered our question and said it was a municipality water cut.
