Housekeeper Needed - Full-time / Part-time

My house is a 3 bedroom 2. 5 bathroom 2 story condo that is approximately 1700 square feet with a loft. My wife and I work and need to free up some time. I work from home several days a week so I may or may not be home when you are here. The 2 upstairs bedrooms, loft and 2nd full bath is upstairs and occupied by our 2 college students children that are only here from time to time, summer, and between semesters. One is here more often because she goes to college in Florida and sometimes comes home on the weekends.
