It is very good to have happy hour every day evening. But i recommend the happy hour to be held later, eg. 9 or 10pm, in summer. Because in summer, 7pm is too early to come back to hostel.
There is air conditioner in rooms. It can reduce the heat, 30 ℃, in summer. But unfortunately, the roommate insisted to shut down the air conditioner once she got into the room. It made the room too hot to stay.
