My sister and I had a phenomenal experience. The apartment is a 2 bedroom literally a 2 min walk from Hagia Sofia and the Blue Mosque. The apartment itself is extremely clean with WiFi and a fully operational kitchen.
Even better than the location and the apartment was the host, Volkan. Think of him as a full service concierge that is there to help make your trip as seamless as possible. He helped us avoid the pricey areas and would ensure we got taxi cabs that weren’t out to scam us. He even received a package for us that we ordered online and made sure all items were accounted for as we were out and about doing touristy things.
All in all, I would definitely recommend staying here. The location/quality of apartment combined with the peace of mind of having Volkan as the host was more than worth it.
