I stayed at Murat place in Istanbul almost 1 mounth. I didn't meet Murat in person, but comunication with him was perfect and very quick. Location of apartament is near center but you have to walk a little or use bus to go in center. There are buses for Taksim and Eminonu but sometimes you need to wait a little for a bus. So if metro would be a little bit closer, than location could be perfect :) Defenetley recommanded.
