The cleaner took DOUBLE the usual amount of time to clean (12 wo/man hours after 1 week's stay !) - only just finishing in time for the next guests because she shipped in a friend half way through.
They've 'lost' all the toboggans and snow 'trays' that we've only had in for 2 weeks.
Divertor knob in bathroom has been broken off and towel rail yanked off the wall.
What gets our goat (sorry GG & MG) the most, is that they didn't say anything to anyone, despite the clause in our Rental Agreement that clearly states they need to. We do have another clause that talks about cleaning and the state we expect the place left in and if it's not, sums will be deducted, which I'm grateful for.
We've never had to make any deductions before (even when cleaning has gone over (but not by this much) and we've had minor damage - if they let us, or the caretaker, know at the time, we're very pragmatic about these things usually).
The other annoying thing is that this was the the last remaining week we had left in the season and we discounted it - in hindsight rather too hastily - and knocked off £250, so they had a bargain.
I have to say there was something about them that made me wary at the outset. To the point that I sent them a note and at the bottom mentioned that we loved our place and it was very precious to us (which I've NEVER felt the need to do before). He even responded back to that saying that 'they'd take good care of it'.
They texted as they left, saying they'd had a lovely time and would be booking again !
Have just sent a 'considered' email asking for their comments and any idea where the toboggans might be as our current guests have none to use and will need to allow the plumber in this week.
There's no way a penny is going back to them until we've had all the costings back and we'll then only return the balance. (OH is all for keeping all of it but I've said that's not really cricket - although knowing the price of Swiss tradesman, it might actually come to it !).
I know that in the grand scheme of things these are very minor things and fortunately things are still working for this week's guests. However, it does rather take the shine off when you have to spend much of the weekend going backwards and forwards trying to sort things out. Then no doubt there will be wrangling over the money.
However, all this ranting is purely my way of saying - ONE SHOULD ALWAYS TAKE A SECURITY DEPOSIT !!
Right, rant over.

I think you really must keep some or all of the security deposit. As LV says, the sooner you can let them know how much you'll be deducting, the better.
