"The cleaning was excellent! They both did a very thorough job and my home looked and smelled excellent when they were finished. We have two dogs and not a trace of dog hair was left when they finished. They wiped down and dusted every surface, vacuumed the dog beds and crates. Very friendly and looking forward to having them back again!"
