I scheduled the cleaning about 2 weeks out, and it ended up being the day after the worst of Hurricance Sandy. The team was running late, but I was called about it well ahead of time.
They ran down the list of areas I gave as priorities and made the bathrooms spotless, which was what I really cared about.
The chemicals used are a bit strong and took half a day to air out. I wouldn't expect that to be different from other cleaners, though.
