Mauro is an excellent host! He is very kind, friendly, helpful, communicative and respects your privacy. My room was very cosy and clean (perfect for a solo traveller like me), I had everything I needed so my stay there was more than comfortable. The location of Mauro's flat is also great - less than 10 minutes from the Duomo, close to Mercato Centrale (a market with fresh Italian food), close to bus stops and bars / restaurants.
I highly recommend Mauro's place!
