They don't list the room sizes online, but the Deluxe Double Balcony Room is 24 m2. That does not include the balcony. The balcony is shared with another room, so make sure you lock the balcony door. There's no chairs or table on the balcony for you to sit and relax so the balcony is just a waste of space. There's no elevated platform for your luggage so you have to put your luggage on the floor and bend down to get your clothes. There's a desk and a chair, but the chair is hard so it's not comfortable to sit on for long durations. I borrowed a softer chair from the restaurant for the night. There's coffee and tea making facilities in the room. The closet has two bathrobes, which is a nice touch. One side of the bed is up against the wall, which is a bit awkward.
There is a building next door that blocks your view from the window so make sure you get a room on a high floor. I got room 702, which had a nice view. I'm not sure if room 602 would clear the roof the adjacent building.
If you walk around the block, there's nothing much going on except for KTVs. For eating, look for the nearby barbecue restaurant.
They use these industrial ceiling mounted wifi routers and repeaters that leave you no option to hardwire if the wifi is slow. Fast enough for reading, but not for watching videos or voice.
There's a pool and gym as well.
Get a room 6th floor and up. Anything below there's a building next door that blocks your view.
