Positive- the staff were helpful and friendly. For a solo traveller, the facilities were everything I needed. A bed to sleep in, warm shower and security. Only 1 minute walk from the subway, McDonald's, a bakery, a juice shop. Myeongdong is a great area with endless shopping across the road from the Hostel. Under bed locker was large enough to fit my big wheeler luggage. Room keycard and locker key were great. I didn't get to take advantage of the daily free breakfast. Actual bed area was great. Generous room space with a shade for privacy. Blocked out all light.
Negative- If you have a problem with "sharing" a shower with someone, then this place may not be for you. Small frosted partitions between the 3 showers in the shower room. It wasn't a problem for me but there was a girl who kept looking out for when the shower room was completely empty so she could feel comfortable. The busy rush hours from 8-10pm are heavy. Lots of girls coming in and out of the bathroom, toilets and shower rooms were messy at those times. Also, most girls are awake at that time so if you sleep in, you may be disturbed with all the coming in and out of the room. However, these are all understandable since it is a Hostel.
Overall- enjoyed my stay! I'd definitely stay there again.
