Only volume 1 is scanlated, 10 chapters. 15 volumes available. What a pity though. Though it's quite fantasy-like, it's actually enjoyable, with a housekeeper like Mirano.
Romance, housekeeping duties seem to be featured in volume 1.

Story:8
Original concept. Started off with impact as well, and up to chapter 10 we can see more of Furuda's likeable personality and skills. The story notes the trust and bonds that housekeepers and their clients share, and sometimes sparks are created as well.

However, the story seems to sometimes have problems solved too easily, or things unresolved. Plus, Furuda seems to experienced for her age so it's kind of eerie, and up till now the housekeepers featured are very young. Could be more interesting for an age variety.

Art:8
Facial expressions are superb, one of the better ones out there.
Background drawing is average.
Most panels are understandable.

Character:6
Doesn't seem to be much of character development of main character, other than dislikes of spiders and personality, and some past.
Most of the characters featured up till now seemed to be just used as extra characters, not really unique.

Enjoyment:8
I enjoyed dreaming... lol. Such an excellent housekeeper, are you sure it exisits?
But well, some jokes cracked were quite funny, and the romance scenes do not seem out of place. Story-telling method was smooth and natural.
However, soemtimes a bit dull.

Overall:8
This is one manga you can pick up for a light read, or to find out more about what housekeeper's duties are. In vol 1 there are some notes about housekeepers, likely to have more in future vols.
