You should watch Gran Hotel the original Spanish one. You'll have to sign up for a Spanish language streaming service like Vix+ (used to be on Netflix) but it's the greatest show ever! It's so many things - mystery, romance, drama. Set near the beginning of the 1900s so it's gorgeous to look at. Premise is that young poor man shows up to a fancy hotel where his sister had been a maid to find out why her letters stopped coming and where she is.
