Good appartments in Istanbul. Near the big mall. Subway is 10 minutes close, a lot of public transport/taxi can be found. 20-30 minutes by car to the tourist European side. Internet connection is good. You may work at the balcony with a good view.
Windows is to the North, so no Sun in the view, can be good or bad.
Mosque is very close, so can be loud at 5am.
