I'm an American and this is my first time in South Korea and this was 1 of 3 hotels I stayed at during my time. The following was my experience and observation.
Pros: Very close to the Busan train station (5min walk), clean, quiet, relatively big room for the price you pay, large bathroom with separate areas, bedside lighting controls, mini fridge, safe, personal computer and TV (both we did not try), multiple universal charging stations for your phone or batteries.
Cons: No hot water in bathroom sink, jacuzzi is small and jets did not work, nor is the jacuzzi large enough to fit more than 1 adult with their legs crossed, if arriving late hard to contact front desk but someone is watching the lobby through surveillance somewhere so you just got to wait. Lobby is through the garage area which was completely dark when we arrived for check-in so it was a bit sketchy.
Weird/different: When entering your room you must put your keycard in a slot that then activates your electricity in your room (lights, tv, heat/ac etc). In this particular hotel your room number outside is lit up Red or Green Green means empty or the room keycard is not in. Red means the keycard is in and it's occupied. So it's kind of odd that anyone can know if you are in your room or not. The keycard is a normal thing in all 3 hotels I stayed at.
Overall our stay here was pleasant once you got used to the features and amenities. Lots of convenience and food nearby!
