My friends and I stayed at Mattia's place for three days. We had a wonderful experience, as mattia was a welcoming and responsive host. The place was really spacious and clean, easily accessible by train or by foot to places like the port. It is only lacking several things like toiletries and dishwashing liquid if you were to use the cutlery, which can easily be circumvented. The one negative would be that the bedrooms are overlooking the street so the street noises could be heard at night.
However, as a host, she went above and beyond to help us during our stay, and was very responsive when we asked for help. She was accommodating and nice. Overall, we had a great stay and would highly recommend giving this place a shot!
