I booked a Deluxe room on Hotels.com which was listed as being 35 m² with a bathtub, I measured 33.5 m², which is about right, but no bathtub. The attendant mentioned there must have been a mistake on their Hotels.com listing.
This place has a predominantly Korean clientele and they are notorious smokers. The first room they showed me look very spacious and nice, but the cigarette smell was off putting. They gave me another room that didn't have the smell. It's funny how they have a big sign that says no smoking, but right next to the sign they have an ashtray.
There's an ethernet port in the room if the wifi is not fast enough for you. That's always a nice touch for business travelers.
The bedding was large and comfortable.
The floor to ceiling windows had a nice view.
They have an a la carte breakfast instead of a breakfast buffet. On hotels.com they charge more money if you want breakfast, but the attendant didn't ask me what room number I was in so it might be possible to get free breakfast without paying extra for it. If you are a low carber, then the continental breakfast has bacon, sausage, and eggs. The Kimchee stew is also carb free.
You are in Koreatown with a bar on the corner. If you go outside at night, wear long sleeve because mosquitoes.
Room Tip: The deluxe room was very spacious with a nice view. Don't expect a bathtub, though.
