The location of the apartment is very good. The transportation is convenient and the view is great. I saw the sun rising over the Asian district in the morning and the sunset over Hagia Sophia in the evening.
It was a bit inconvenient that the accommodations around the Galata Tower are mostly on hillsides and there is no elevator. However, because of the location and view, all of my friends agreed that the inconvenience was minor.
Karakoy ferry pier is a 5-10 minute walk, and Egyptian Bazaar is across the Galata Bridge. The mart is close and there are many restaurants around.
However, there are 4 rooms, but the living room was a little smaller than it looks in the picture. That doesn't mean it was too uncomfortable. Kitchen facilities were all good.
Communication with the host was very good from reservation to check-in and check-out. Special thanks to Mr. Ahmet.
