The rooms are pretty nice, beds are super comfortable, the bathroom was amazing. The price was incredibly cheap, if you're unbothered by the bad stuff below, it's definitely worth it just for the cheap price. Just a small note: I'm from Sweden so I'm comparing the price to typical European hotel prices.

Breakfast was extremely limited; you had coffee, toast and ramen, that's it. It is absolutely not an "American breakfast" as Booking wants it to be. The location is absolutely horrible, taxis will have a hard time finding you, and you'll need to walk for 30 minutes to find the nearest bus station. There is no real reception available, most of the time the person sitting there is gone, so you'll have a hard time reaching them. If you don't speak Korean, you'll be having a very hard time communicating with the staff or getting around the area.

My room had a wonderful big bathtub and shower facility. Rooms seemed completely soundproof ( important because there is a busy highway outside). The rooms were spotlessly clean each day. I could watch some free movies on the TV and I appreciated the tea and coffee making facilities,

This hotel, though very comfortable, was too remote from Busan for someone dependent on public transport. I was warned of this ( by the staff) before I arrived) but assumed there would , at least, be a bus connection to down town. There was a connection but very irregular. The availability of buses was better in the morning but futile in the evening.
