The apartment is in the old town of Istanbul. Walking distance to Sophia, the blue mosque, the bazaar and the tram. It is not in the typical touristic avenue, but one that makes you feel you are living in the city.
When we arrived, a cheerful man, Alli opened the door and helped us settling in. He gave us a map of the city and the tube and told us basic but essential information on how to get around and what to see. He also made sure we were doing fine everyday and helped us with the transfers for the airport. ( He even walk up at 5.30 to make sure we were in the right bus). He really made us feel welcome and comfortable.
The apartment is clean, new and nice. The beds are supper comfy, the shower has good pressure. They also have a quite complete kitchen.
The only little but was the hairdryer that, as in any other hotel is not too powerful.
Overall, I highly recommend the place.
