I've recently become acquainted (online) with a German lady who spent a month in London last year. She said if I'm planning to go back, to let her know, because she found a terrific flat in Lambeth through Wimdu. I was telling my husband about this, and he brought up something that hadn't even crossed my mind.
Safety. Not the sort where the host turns out to be an axe murderer, but the kind where the place isn't really meant to be rented out. In other words, if you stay in a hotel it will (hopefully) have clearly marked exits, a back-up generator (possibly), fire stairs, fire extinguishers etc. If you're basically staying in somebody's home, they're not going to have all these things.
Of course it's often much cheaper to stay in a flat or house, and maybe this is the price you pay (no pun intended).
What do you think? Do any of these agencies inspect for situations like fire?
Thanks!
