Everything was so wonderful and clean (so clean!) and beautifully appointed. The area is perfect and as described, close to many attractions and cute shops and a ~10 min walk to public transit, but quiet and away from the crowds at Galata Tower or that you'll see in many of the tourist hotspots. The area is so picturesque and a delight to walk around. The apartment has a modern aesthetic without being cold--it feels very warm and cozy due to the wood and exposed brick design. The host was incredibly communicative, helpful, and flexible. My stay was literally a highlight of my time in Istanbul. I have no complaints. If I find myself back in Istanbul I would definitely stay there again and would highly recommend others do so as well.
A note on accessibility: I think this would not be a suitable location for someone who couldn't walk up 2 flights of stairs to get to the apartment, as I did not see any elevator available. Additionally, the Airbnb is situated uphill and the area is paved with cobblestones. One could use a taxi to go to and fro, but just noting for those for whom that might prove difficult to traverse constantly and who might prefer a flatter terrain for walking.
