Our morning devotionals and our evening meetings were out on the balcony, as well as random games or worship. It was a nice spot to sit and have quiet time, and everyone generally respected your wish for privacy when you sat facing the view with a book/bible in your hands.
The hostel was fenced in with a guard always present, so we were very safe. But from the balcony, we could watch the people and traffic go by, as well as hear and be heard by those going by. This sometimes meant it was hard to hear each other in the evenings, or that people would randomly yell comments at us.
