1. Regarding Indian schools the best Indian school in DPS-MIS. The second term starts from September. Better to check with the school and let them know that your kid will be joining in October, as he is small class it wont be a problem.. you can check other schools

2. If you are working in Almana Tower, the nearest locations are Old Airport area, Hilal, Najma, etc. Rent for furnished two be apartment cost around 8.5 to 9K. There are some good play schools near Old Airport and Hilal. But I don’t think you can walk in this climate. When you come here you will know that. You can arrange pvt taxis for daily pick up an drop off.
