Dualis Hotel is a great place to stay in İstanbul. Selim is very supportive person. Gulzoda who manages the facility makes everything easy and available to you. She surprised us with a very beautiful cake. All the family enjoyed the stay. 10 minutes walkable to Sultanahmet Area and to the tram. There is a couple of parks few steps away where you can stay and enjoy fresh air while kids can enjoy free rides. Supermarket & restaurants are also nearby with walkable distance.
