Considering doing this for our new spare room (which has en suite, TV/internet access, etc). Had considered it for an au pair/live in nanny but it may be that we can get more for the room than we would save having the nanny live in. Also, aspects of our track record with nannies are a bit uneven, and not sure I'm sold on this option. We are still running the numbers.
How livable is it to have a lodger around do you reckon?
