Safety and Comfort - First Timer Tips

Good evening. I’m about to embark on my first travel arrangement. Obviously, I know I’m a safe, sane person. But I was curious if there are little (or big things) I could do to help ensure the provider feels the same way about me and that she’s comfortable and safe.

I know I’ll be allowing personal time, comfortable sleeping circumstances, and clear communication, but I was wondering if anyone had advice for things they like to see, hear, receive from a client to help everyone feel at their safest and most comfortable.

I’m also curious how to handle my privacy and safety for a stay. Is it rude to use a hotel safe without sharing access in a circumstance like this? Are there signs I should look for to know if something is amiss? I don’t have a predisposition of a SW being a bad person at all, just want to make sure if I am acting a certain way it’s not rude.

Thanks in advance for any help.
