In both manga some dude lives in a big mansion with various monster girls and that's probably all you need to know. Ashita no Familia is very timid in terms of fanservice when compared to Magetsukan Kitan, hence one-sided recommendation.
If you want to read a manga in which a male lead finds himself surrounded by monsters (mostly cute female ones), but which is far less ecchi, far less harem and way more fun, then you ought to read Kaibutsu Oujo. It also features some action (as in fights), mystery and there is even plot.
Fifteen-year-old Tsukune Aono is average in every way; he has no hobbies, less-than-stellar grades and he's even flunked his high school entrance exam. His parents have managed to enroll him in a school, but it's no ordinary school! Tsukune will be attending the Youkai Academy, a place where monsters learn how to co-exist with humans! As the werewolves, vampires, witches and other monsters are required to retain their human forms, Tsukune - the lone human - is able to avoid their bloodthirsty gazes. However, he quickly attracts the attention of a number of devilish beauties including the vampire Moka, a busty succubus and even a young witch! It seems Tsukune's average life isn't so average anymore!
