I stayed at Eminönü's flat for 5 days. He was accommodating, diligent, and responsive. He allowed me to check-in early. He briefed me with information needed for my stay at his place. And he replied to my additional queries on time.
Eminönü's flat is as described and pictured in his listing. It is located in a quiet neighborhood with grocery stores, a café and a restaurant nearby. Within 10 minutes, you can reach İstiklal Avenue as well as public bus stops on foot. The flat was nicely decorated with antiques and came equipped with a fridge, an AC and a washer.
Why not a 5-star rating? There were issues and I will list them in order of importance to me.
1) The water pressure in the shower was very, very low. It was so low that water temperature was a non-issue because very little water was coming out.
2) The washer was in my room on the 2nd floor while the complimentary detergent was on the ground floor. It would be more convenient to have some detergent in the flat.
3) The AC did its job during my stay but its setting was not stable - it kept on changing modes.
4) There was no water from the kitchen faucet the entire time. It didn't bother me as I didn't cook during my stay and I used the one in the bathroom when I needed to.
5) I didn't see the dryer. It was a minor issue as I ended up hanging my laundry on the roof. The roof, by the way, is not well-kept. One has to watch where they step.
All in all, if you want a central place with some amenities for a couple of days in Istanbul, Eminönü's flat is a fair option.
