When you made a reservation in this hotel, you remember that you should receive the receip of city tax. Or not, YOU BECOME A LIAR OR PAY DOUBLE!! When you check in they request you a city tax. I know there is a city tax. So I paied it without any doubt. It (pay city tax when check in) is nomal rule in Italy (at least in venice and firenze as i know). At that time they do not give you a recipt of city tax(This is not normal! You should receive it). And then when you check out they request you city tax A.G.A.I.N!! Even I explained I already paid the city tax when check in and she who handled my check in didn't gave me any receipt. He who handled my check out never belive me and look at me like a liar and request city tax or evidence again and again!! Of cause I didn't pay twice! But he was very rude!! I never forget his face 'oh my god, tell a lie to avoid city tax?!'. It is not a big money (it only 3.5 euro per day!) but he screwed up my venice trip. (I just visited italy to see venice from korea. Venice was my main journey during my 6 days vacation. I staied 5 days in venice. And this is my second time in venice.) Please be careful! You also can become a liar or double pay city tax.
Plus, wifi is almost not working in the room! Only first wifi circle is on and sometimes not working.
