The apartment is one of the best we ever booked through Airbnb. Probably the best one!
Superbly clean and well equipped. View over Bosfor is breathtaking. A little noisy outside but it's what you should expect in the heart of Galata. No elevator is not really a big problem here.
Hosts were super helpful with check in, helped with airport transfer, quickly responded on messages. We really felt as guests with friends or relatives here :)
Next time in Istanbul we definitely check this apartment before looking for anything else.
