I loved this hostel! It was so cute and very nice. There's a lot of dorm rooms and the common area is very big! Each room has it's own bathroom and shower, so you don't have to share a big washroom with a whole bunch of people. Each bed has it's own private curtains, as well as a small light and plug. There are lockers for everyone in the room to lock up important things. The staff are very friendly and caring. They thoroughly clean the building and rooms every day. There's a fully stocked kitchen you are free to use (fridge, stove, microwave, kettle, coffee machine, plates, pots and pans, etc.). There's also wifi everywhere in the hostel. It's in a great location in Haeundae, right by the Fish Market and about a 5-10 minute walk to the beach. I would definitely recommend this place!
PS the bed mattresses are typical Asian mattresses, they're super hard.
