Response from Zara:
Monica. I think there must be some sort of communication breakdown. I didn't "demand" money back - I simply said that if you were scheduling annual boiler maintenance during our stay it might be fair if you might consider waiving some of the 50 EUR fee you charged for us arriving at 21.30 rather than 20.00, to which you replied you'd rather change the appointment (so it clearly was possible to do so). It isn't about Italian law - of course you're allowed access to your property - it is about the fact that you are renting a holiday home for people on weekend breaks/ short term breaks and to have a boiler repair during that is inconvenient to the people staying there. You ought to recognise that somehow. We wanted to be in the apartment on Monday morning, and to have had a boiler maintenance person there isn't conducive to a relaxing holiday!
As I said in my review, the apartment is lovely but your attitude made a holiday very difficult. As for the shower breaking down, there was no need for an "emergency plumber" as you stated - you simply needed to provide another shower head and cord, which you did once Air bnb called you and told you that you were in the wrong. We could have fitted it ourselves.
I wish you all the best, but I must say I find your personal judgements about "trying to pay a little and then trying everything to recover some money" unnecessary and insulting.
