I unfortunately missed my flight to Florence and did not get to stay at Mauro's place. But I have to say he was very helpful and understandable. I told him that I might be arriving later than 12am and he was very kind and said he will be there and willing to wake up at any time to open the door for me. Like I said, I didn't make it, but I'm glad he was willing to work with my crazy late arriving time. He also explained that it was too late to get a refund through Airbnb but was more than happy to give me half back if I stopped by any of the next couple of days. I'm sad I didn't get to stay at Mauro's place since he seems like a very nice and kind person.
