Just started watching this today, it's a Korean telenovela consisting of 16 episodes ... my mom likes it, she binge watched on 9 episodes already, I'm only done with the first 3 episodes but it has an interesting storyline
Located in the middle of Seoul, Hotel del Luna is the eponymous hotel that caters only to ghosts; the beautiful but ill-tempered CEO is cursed to manage the hotel due to a terrible crime she committed, but cannot remember.
Here's a link to the full trailer -
