So, Magetsukan kitan, a "little house of horrors" (make that a big house actually) that strives to show you that not all monsters are, well, monstrous but are actually trying to survive any way they can.
The main character is a basic protagonist (nice guy, not particularly muscular or good looking, you know, the usual harem-style MC) who's just moved to the city in search of a job, but to do so, he also needs somewhere to stay. Sadly, he doesn't have tons of cash and all the offers he finds at the estate agent's are out of his budget. Except for one, a room for
9000 yen. It seems like a good deal but the room is actually in a monster mansion. So he goes there, falls in love with the landlady, freaks out, tries to leave then stays for good when he realizes than these monsters aren't out to get him. A sort of slice of life ensues.
The story is fun, if you like slice of life's with a horror/dark fantasy twist to them, there is a certain amount of ecchi (which gets near borderline at a couple points) and all the characters have their little quirks and backstories and are very enjoyable. The art is good, possibly a bit rough 'round the edges here and there, but nothing that would stop the reader from enjoying him(or her)self.
If I had to compare this manga to anything else, I'd say it would be close to Love Hina, with a touch of Rosario+Vampire's early days. Either way, if you're looking for something nice, with a bit of fantasy and harem action, you should read this series.
The only problem I have with this series is the fact that you can only find scans up to chapter 37 on most manga reader sites, so if anyone knows where the whole series can be found, the info would be very welcome ^^
