Hello and welcome. You might want to read through the post on clean house, where this topic is discussed.
As @Kelownagurl has said, members - sitters and homeowners - are unlikely to agree on what is seen as clean. However, providing realistic photos and having an honest discussion with prospective sitters is always important. Some sitters will be attracted to a home that looks like it came out of a designer magazine, whereas others will steer clear of those as they don’t feel they could relax there.
