This place totally matches the pictures. Very new, clean, & modern. Felt like we were staying in a brand new spot for sure. The shower is large, hot, and strong. There's a washing machine that we used. The wifi is quick and reliable. The two bedrooms were great to have, even if the twin room is a small one. Overall very comfortable and clean.
The location is pretty great -- you're a 3-5 minute walk from Taksim Square but still on a very private and quiet street. You're also very close to the main touristy shopping, dining, walking streets. There was some noise from techno/club music at night that sounded a block or two away. If you are a light sleeper this could be an issue, so bring earplugs or use a noise machine/app.
The only negative was that, being a seemingly new Airbnb listing, the instructions and extras weren't quite there yet. We had to ask several questions about getting in, accessing wifi, turning on hot water, etc. But Mehmet was always responsive! Very good for price!
