The apartment is really lovely and renewed, in the heart of Istanbul right next to Galata tower. The terrace is definitely a great plus, I recommend going there and enjoy the sunset while sipping your tea/coffee :-)
It's at 3rd floor with no elevator so better not to bring heavy/ large luggage - we were travelling light and didn't have any problem.
Enes will assist you with your stay and he will make everything go smoothly, helping out with arranging taxis and giving advices. Amazing communication before and during your stay!
Highly recommended if you're planning a short trip to Istanbul and want to be in the city centre. Great for couples :-)
