It is important to let the people know that the host ask for money when the guests arrive, arguing it is a tax for Florence, but I was doubting, because this information was not mentioned in the description of the place/room, and I looked into the internet in order to checked if this was an accurate information, and I found she was asking for more money than its has to be (the double), and despite I was telling her that she needed to give me back the money she argued she had an additional "permission" that allowed her to asked for that tax, eventhough I send her the link in the internet where it says the right information. At the end she return back money but be careful with people who want to take advantage of foreigns. Another information important, you cannot use the kitchen.
