I find the 1-star reviews below shocking based on my repeated business and experiences with Emilia and her service. I called Emilia some months ago to set up 1x month cleaning, which I then upped to 2x a month upon my boyfriend moving in. We also used her service for the move-out cleaning for my boyfriend's old place since he had an insane landlord who we knew would nitpick if everything wasn't perfect. These guys really do a great job and couldn't be nicer while doing it.
YES - they do use YOUR cleaning supplies, but Emilia made this very clear to me up front (for the move-out clean, they provide their own since, presumably, you're no longer in the apartment and so there are no supplies there). I'm sure for some people, this policy is annoying/not your preferance. Personally, I like it because I know what products are being used on delicate surfaces, around pets, etc.
Emilia is extremely responsive to email and voicemail and sets you up so that you have the same cleaning person every time (Sylvia comes to my place and does a great job). That way, if there are certain things you're picky about, you can just tell them and they adjust accordingly and you don't have to deal with explaining that again and again to different people. Also, Emilia's staff all speak and can read/write proficient english, which I've found extremely important if you want to be able to leave notes or specific instruction ("please move wash to dryer and clean fridge this week," etc).
At bottom, there has never been something I asked for or expected that they didn't follow through on 100% My place always looks and smells great and everything from my stovetop to closet floors end up spotless. Sylvia will fold what's in the dryer upon request, always tidies my pile of shoes in the bedroom into neat little rows in the closet, and tougher cleaning like mildew stains in the shower or crud in the fridge are always gone without a trace upon my return home. I have no reservations recommending this service - really, really great job and a pleasure to work with.
