I have had good and bad experiences over the years--but to me paying for someone else to clean my house so I have that time to do what I want is so worth it!!! I recommend you go with someone with referrals from someone you know and trust vs an unknown cleaning service. If that doesn't work check out Angie's List ratings for some in your area. Have a 2 or 3 come to your house, do a walk through of what will be done and what won't and get bids first. Some will change bed linens, others will not. What about cleaning light fixtures? Discuss who supplies cleaning supplies and if you have any specific needs--for example I provide the cleaner for my hardwood floors because I do not want any other product used on them. I also hate the smell of Pine Sol! Keep in mind accidents do happen--if you have a lot of breakable treasures sitting out, think about handing the dusting of them yourself. I also have a window washer come quarterly and love to have sparkling windows.
