As noted elsewhere, it was actually Maria Caterina's mother who welcomed me - and she was very welcoming, ensuring I was comfortable, knew where everything was, how it worked and, finally, asking what time I wanted breakfast..!
The apartment is large, suitable for a whole family and very clean and comfortable. Maria clearly takes care of the place and her guests, and I can happily recommend it.
Oh, and the cake was delicious... grazie mille..!
