Hi Rosiesmum,
I am the founder of PetHomeStay and would be happy to answer any questions you might have. :)
To partly answer your question, all the HomeStays on our site are independent. We have a mix of professional sitters, casual and student sitters, and some will come to your house and some only in their own house. So it's really up to you what you want in a service and to pick the right one - we are a free community service, and we don't vouch for any of the sitters at present, but we do ask that people protect themselves and follow our House Rules like requesting to see any insurance or police certificate if sitters say they have one.
Feel free to ask/ DM me any other questions, we have had over 550 enquiries via our site, around 250 nights of pet care delivered so far with a 97% 5/5 rating.
Or come and see us at the Dog Lovers Show in the first weekend in May :)
regards
Tom
