The BEST place to stay in Istanbul. If you like history and want to go sigh siting without spending half of that time on transportation, this is the place to stay. It's a very local neighborhood, but in ten minutes you can be to any of the historic places in Old Town. There is everything you need nearby: pharmacy, supermarket, stores, etc
The place is amazing and super comfortable, plus it has two amazing views, one of the ocean and the old wall and the other of the Blue Mosque.
Celal was also super friendly and cool, always ready to help, and if I could give this place more stars it would be just because of him. I highly recommend it.
