Hi Angela, again the aforementioned son. Partly true what you wrote. Mom answered you, quite limitedly as for her language knowledge but she did it, and hence I've done the possible to help you through instant messaging. I showed you even that merely writing the street name and home number I found the address on my phone, I suspect you couldn't due to using maps in offline mode (you could have had no internet since you were abroad).
Now, regarding cancellation policies. Right, a reservation canceled within 24h shall be refunded, but another rule is that same/next day reservations (24h aback of the entry time, or less) won't be refunded, since another person could have booked by the time you reserved our room. This last rule stays above the refunding if canceled within 24h.
Else. I mentioned nothing about the refund since I hadn't to. As for the rules my mom deserved to obtain the payment, though you still had the possibility to claim it.
I reiterate: I sent you a screenshot of a research of our address on the maps app, if you couldn't find it on your phone, the problem does not concern us... other guests found it, with no need of "'til the door threshold" indications.
Anyway, hope you enjoyed your Italian stay aside from this mishap. Best regards!
