Comfy place, perfect location, beautiful balcony view. Altuğ and Şadman were very helpful, available 24/7 for any messages/calls.
The apartments are fully equipped for a comfortable stay.
The most important thing for us was wi-fi as we were working remotely during our stay in Istanbul. For some reason wi-fi wasn't working when we arrived, but it was fixed within an hour or so. According to speed tests: download/upload was ~15 Mbps average, which appears to be fine for VPNs, Zoom calls and stuff.
Note that the flat is located on the third floor (stairs only). If this is challenging for you, you might also consider choosing another district to stay, as there are lots of stairs in this one.
