Sarah's house is nice, cosy, and well located to visit Venice (in a little street, minimum noise in november).
But something create a bad surprise : we have to pay a "city tax", so we have to pay more than published at the beginning. Even if this is something indicated at the end of the description, I suggest to put the total on the budget we pay on the website.
I am host too, I have to pay taxes : income tax, direct and indirect taxes, I have to pay electricity, household heating costs, etc.. To me it is fair to put the total price at the beginning, because airbnb is not like a hotel :)
