It's a refugee camp with better infrastructure and opportunity. That makes it quite different from what we normally think "refugee camp" means.

Frankly, it sounds like Gaza. Walled off, restricted rights, told they can "just leave" to places that aren't safe or welcoming, etc. Sure, there are permanent buildings, water/electricity sometimes, etc., theoretically some self-determination, but it's still a crowded, dismal refugee camp with little hope of improvement for its residents.
