If you liked one then I think you'll like the other!

Similarities:
-Both MLs just moved to a new place and are desperate for a place to live.
-Both places are rumoured to be creepy/haunted.
-Both MLs believe their studio has something weird going on and that their neighbours are at the core of it.
-In both, there are moments where the ML is very close to danger but is oblivious to it e.g someone standing with a knife outside his door that he spontaneously chooses to not go through - similar tense scenes appear in both shows.

Differences:
-some romance in TJACTN (but suspense/thriller is still the main theme)
-in SFH the ML really wants to leave but in TJACTN the ML wants to stay and find an explanation for what is happening
-ML from TJACTN is a med/psych student so his investigation is more logical and analytical than the ML's from SFH
-SFH only really focuses on Eden studio but TJACTN has more subplots (e.g. ML has 6 months before he might start showing symptoms of schizophrenia, he is studying med/psych to prevent this; ML investigates the life + cause of death of the previous tenant much more)
-in TJACTN people actually believe the ML when he says something is weird! He also has friends that help him
-Cha Cha in TJACTN makes some situations less serious compared to the constant tension in SFH

I found the first few episodes to be remarkabley similar!
They both feature desert scenes where one person saves the other.
Both MLs also hide their true identity and both FLs are princesses.
Both also have a marriage alliance and devoted MLs.
Definitely recommend if you're looking for a drama to fill the gap after Princess Jieyou or Goodbye my princess.
