Does anyone know how to write a letter that meets all the requirements to act as Proof of Accommodation? I'm staying in London over the summer with a family friend for my GAE visa, so I have no hotel booking or rental agreement to send.
Does anyone know what would need to be included, besides their name, address, and signature?
I saw something about having to provide proof of residency, but I really want to avoid making them send extra documents for no reason.
Thanks in advance!
