I had a very pleasent stay at Hatice's apartment, and would gladly stay again!
For the price, this apartment has everything you need! It can be a little cold, though with the heaters provided by Hatice you could keep the bedroom at a good temperature! The bed was comfy and there were plenty of blankets. The Wifi worked well, and was good enough for video calls as I was working remotely. There were only a few limited power sockets, but that is expected in an old building in Turkey!
It is very well located, just a 15 minute walk to Taksim and right near many good shops and cafes!
