seeking a good hotel for short stay - 4,5 days (Istanbul)

Hi all,
I am going to visit Istanbul in March and want to get some ideas where and which hotel would be recommendable for short stay.

I checked several website such booking.com, etc.. but I am not sure those photos attached are real one or not.

Preferable place would be in the center, very good access to business town, amenities. No dangerous, noizy, pub area...

appreciate your advice!
