i'm leaving my original review below, but am updating it because i've found that they are not as great as i thought, or their work has gone downhill since they started working here.
they are still nice, still come on time, still bring their own stuff, etc. but the last few times they were here they did a sub-par job. once i walked in and didn't even realize that they had cleaned one of the levels of the house - it just wasn't all that clean, didn't smell fresh, etc. and last time they were here they failed to wipe off a dusty dining room table, didn't mop the kitchen, etc. t
luckily the woman who cleaned our home for years is back working, so rova is no longer working for me.
john and roxanna are terrific. they come on time, clean everything they can see, bring their own products, work quickly, and are nice. they often will do extra things like clean out/wipe down the inside of the fridge - even without being asked.
and once they had to cancel and i was in a rut - having 40 people over for a party in a few days. so they came over the day of the party to clean the house, and that's usually their day off.
very trustworthy, and i highly recommend.
