If you liked Downton Abbey, then you'll LOVE Gran Hotel. It has romance, mystery, murder, and so much more. The show is set in this super fancy hotel in Spain in the early 1900s where a lot of weird stuff goes down, starting with the disappearance of Cristina, one of the employees. Julio, Cristina's brother, goes there to figure out what happened, but quickly discovers there's more than one secret trapped in the fancy hotel. There's also a ~boy meets girl~ love story intertwined, except the boy is poor and the girl is rich, and that's frowned upon at the time.
Rating: 8.5/10 on IMDb.
