Only tangentially related, here's the meat of an emailed reference I received this summer from the former landlord of an applicant, in response to my email inquiry. I found it striking because I could not imagine any American writing this. I approved the applicants but they found another place they liked better. If you get a response that is in any way similar please share it!
Thank you for your message and for your confidence. I can only warmly recommend ______, who are excellent tenants, punctual in payment, very clean and pleasant. If they had wanted to stay a third year in Paris, we would have been delighted to rent them our apartment again.
They are very serious and trustworthy people, and _________ and I have nothing but praise for them.
We hope this review helps, and send you our warmest regards,
