Joao didn't behave nicely when we left our sunglasses in the flat. We had some time left before going to the airport and we hoped we could just wait for an hour for the cleaning lady who lives on the upper floor, as we found out the first evening when we needed a corkscrew. Joao kept insisting on 25 euros, even if at the time it was clearly written on his statement that it was only for "lost keys and postal reshipping". He made up an excuse and seemed very bothered, he told us that we had to understand him as he needed to call some professional cleaner that would have surely charged him for this. In the end, we lost our glasses because of his greediness.
