I lived here for two nights. Really good location and easy to find it.
Cheap so should not expect much .
The first night in a 21-bedroom. Because there are many people living in one room so the air is not very fresh but it is quiet, except some noise at midnight caused by other roomers. Also the bed is not too high and I hit my head on the bed accidentally.
The second night I chose a 10-bedroom which means higher bed space. The air is more fresh BUT this room is next to the road. All night loud noise caused by passing cars and another reason is the open window, haha that is why the air is fresh. I see some roomer wears headset but I am not used to headphones when sleeping. Besides I saw that this hostel provided free earplugs.
Overall, you will be arranged a room randomly. Who knows what will happen. I did not have a good rest but it is cheap.
