This is by far a LUXURY air bnb with the kindest host, who also has great communication skills, available on whatsapp almost all the time. The apartment was HUGE and everything was in such good taste- we loved cooking in the kitchen with the view of the bosphorous at night - Handan had made sure all cooking utensils, crockery and equipment were availabile.
There's a grocery store under the building with all essentials and a tram stop a few steps down that takes you to all the main attractions ( Sultan Ahmet, Spice Bazaar, Galata Tower, Archeology Museum, Grand Bazaar and Galata Port). The location is walking distance from Dolmabache Palace and Besiktas Port- you can get a ferry and explore new areas like Kadikoy and Ortakoy. All these using one Istanbul Card that you can top up using cash at any of the tram stations.
The only effort is the 6 stories you need to climb up to get to the apartment- but the view, quality and size of accommodation and convenient location made it all worth it!
