Clean, well kept hotel in a good, central location.
The reason for the lower review score is that they do not have parking at all, which was not made clear in the Korean language descriptions. The descriptions indicated availability of a parking lot that is wheelchair accessible, which was interpreted to be a parking lot with accessibility capabilities. But in actuality, this meant that there is only one single parking slot (for those with disabilities) available at all. As nearby parking options are all very pricey, this did mean that a hefty additional fee was needed for overnight parking.
To be clear, the room itself was quite clean and the hotel may be a good option for someone without a car who is doing business in the City Hall or Myeongdong area. The staff was professional and otherwise friendly, but were strict to their policy of no refunds, despite multiple attempts from Hotels.com personnel.
