"First of all, since it is newly built, the facilities are clean and nice. The bedding is also good, so I thought about buying a mattress next time at Sono Season. The ocean view is amazing, needless to say. 
What's disappointing? I'll tell you what I feel needs improvement. First of all, since it hasn't been open for long, there may be some things like that, so I think we should take that into account. 
1. Elevator 
I used the hotel, and there are 3 and 2 elevators on each side, but these 5 are not connected, and 3 and 2 operate separately. Usually, since both buttons are pressed, even if the person goes down on one elevator, the other elevator stops at the same floor, so the elevator stops almost every floor. It seems slow.. 
2. Check-in 
The lobby is like a market with a lot of people.. 
I think there will be a lot of complaints, considering the number of people. People waiting behind are sullen..
3. Swimming pool
We paid a lot of money, 40,000 won per person, and I'm generally satisfied, but
it says on the website that aqua shoes are required, but almost no one wears them. The lifeguards are friendly, but they only say it's slippery and don't really mention wearing aqua shoes. The floor is slippery, so there will be a safety accident sooner or later.
4. Room structure
It was a deluxe ocean view, but the toilet is very narrow..
The washing area is on the opposite side, so it's a bit inconvenient
5. Room service
There's no menu or anything...
It seems like you can order by calling the counter, but the menu doesn't seem to be available yet
I don't know what's there or how much it costs"
