Thank you very much for your nice feedback Virginie, it was a pleasure to host you girls in my apartment.
I am glad you girls found the apartment and its surroundings of your liking, you will always be welcome back in the apartment.
In fact, I am sorry to hear that you girls did not expect a charge for the "Tourist tax", which, as stated in the announcement of the apartment, is €3,5 per night per person, and is due by all guests older than 10 years of age.
It is something that I, as a host, have to pay directly to the municipality of Rome, thus it is not a surcharge I apply to my guests.
Besides being clearly stated in the announcement, it was eventually repeated (as a courtesy) in a welcoming email I sent you.
I am sorry this issue did not let you girls enjoy in full your stay.
Ciao and thanks for your kind feedback,
