thank you very much for the feedback.
I am glad you liked the apartment and enjoyed your stay in Florence.
Yes, I work for a company managing quite an amount of apartments in Florence and elsewhere. My apologies for the communication flop - I didn't see your first message immediately, and when I tried to send you an email, it returned (apparently, there is a bug in the system and some messages are not delivered). Will do my best to improve this part of our service and make the communication as smooth and easy as possible.
As for the invoice, the system erroneously summed the city tax of EUR 30 and Airbnb commission of EUR 15,60 in one invoice. You already paid the entire amount to Airbnb upon making the reservation, so please disregard the invoice you received. Your booking was fully paid, and there is no pending charge.
