Hi @Laurie17,
They will not be able to leave you a review as you are different hosts and this also has a lot to do with the interaction with the host.
You could ask them to provide you a reference but then again, I would think this would also have somewhat to do with dealings with you which they have not had. If you want to look at getting references, you can check out the Help Guide on References by clicking the link below.
