My wife and I recently stayed near the beach in an apartment under an elderly couple's home. All the reviews mentioned how friendly Bill and Betty (I can't actually remember their names) were and how much they enjoyed visiting. That was the last thing we were interested in. So in our comments to the hosts we said we were coming to get away from the kids and were just looking for time to ourselves with no interaction from other people. Fortunately that worked! Other than briefly talking to them when we checked in, we didn't interact with them at all the remainder of the time we were there. It was great!

> just want to quickly lock yourself in the rental and have some time alone

There needs to be some way to indicate that the guest wants minimal interaction, or that the host wants minimal interaction.

It is awkward when the host is nice, or trying hard to be nice, but actually you don't get on with them (I often get this with twee people).

I've stayed at places where the host almost seemed to be treating AirBnB as a dating agency. It's never been creepy, but it has been a tiny bit awkward! I remember one place where a young student host had hooked up with a guest, which seemed dodgy (although not my place to judge really!)

Okay but what's to stop at the very least an "opt in/out" feature?
