A few days prior to our stay, the host sent us a link to their private portal to provide photos of our passports (front and back) as well as requesting a 300 euro damage deposit or 30 euro insurance worth up to 300 euros worth of damage. In addition, the host wanted us to pay tourist tax (again, even though it was included in our initial payment). The host was harassing us to upload photos of our passports and stating that it is the law to send photos in Italy and sent me a link to a reddit page. We had expressed that we felt uncomfortable providing this information on their private portal but would be happy to give them our names/passport numbers through airbnb and then show them in person at check in. The host would not allow this and continued to threaten to not give us the keys if we did not do this. We understand that Italy needs this information from tourists, but we decided to cancel this stay as the host made us feel uncomfortable. We stayed at a hotel who only took our passport numbers and names and did not take photos of our passports. In the end, we got airbnb involved who informed us that this host was not abiding by airbnb policy and was not allowed to charge us extra fees outside of airbnb. Would not recommend.
