Melis and Fatih were great hosts, super helpful and devoted to their guests.
The apartment has everything one might need. I booked Galata as per friends recommendation, however only a few days later I realized why that was such a good move. You stay close to all the sightseeing spots, but still get a good night sleep and are not among the crowd all the time. Our street was probably the most quiet one at Galata. Tons of fun places to go get breakfast, either hipster, traditional or Lebanese, super short walk to weather tram or metro, and best of all a great location for a walk across the Golden horn to spice market, Sultanhamet etc.
In short - GREAT location, GREAT hosts. All you need for perfect stay :)
