Would it be worthwhile to add 'Can accommodate' to the profile if it is available?
I have seen this on profiles on other sites in Europe.

Has anybody used this an an alternative accommodation while travelling?

Lets say I was going to Galway or Limerick for something and it required an overnight, then booking in with a lady instead of a hotel might be an option.
Would be difficult to show this on your expenses claim.
I am just thinking out loud. Probably work best if you know the person from before.
