This is a fantastic place to stay in Istanbul! As others had mentioned, it’s very conveniently located but on a quiet street in a very charming neighborhood. I was only there for 2.5 days but covered a lot of ground thanks to its location.
You can tell they have the guest in mind with their set up as it has everything you may need - iron, hair dryer, fan, towels, slippers, kettle, tea, coffee, etc. Even an adapter for my US appliances!
They were very helpful in arranging airport pick-up and anything else I needed for my stay. 10/10 great place!
