THIS IS NOT A 3 STAR HOTEL.
This is at best a 2 star hotel. And an uncomfortable one at that. The amenities all actually belong to the Sea Cloud Hotel (the elevator does also). The pool is not free, you get 2 tickets per day, which lets 2 of your family members go to the pool, and then you pay for the rest of them. You get 4 coffee cups and have to pay for more cups. You also have to pay for plates, bowls, chopsticks, silverware, and cooking utensils even though the room comes with a stove.
The hotel itself is really inconvenient. There aren't any signs readily visible from the curb. not even my taxi driver knew where it was. He said "Go ask at Sea Cloud, it might be a mistake." You have to take te hidden elevator to the 4th floor, go past the desk for Sea Cloud to the other elevator, and then take that elevator to the 6th floor to check in to Sun Cloud.
The room felt like a doctor's office. The lighting was cold, there's no decorations to speak of on the walls, no carpet. All of the places that looked like they'd be closet spaces to put your clothes were sealed shut. The shower had no pressure and was tiny. The floor was actually slippery. Even in bare feet.
This hotel's plus side is that it's right by the busiest part of Haundae Beach. If you're into that, there are alot of touristy drinking and dining options nearby, complete with all the noise. You can easily go drink your sorrows away, but be careful not so slip on the floor when you get back to your room.
