We had a very pleasant stay at Michele apartment. We did not meet him personally (we were welcome by his parents), but he was very reactive before and during our trip. He obviously is an understanding and responsive person.
The apartment is simple but fully functional, at last floor with a lift. We had a one week stay there and all the nights were very quiet.
It is perfectly located: in Santa Croce but right at the border with the very central part of the city, therefore in a central but quiet place a few steps from everything (we really appreciated not being right in the middle of the city as it was very crowded, but we could reach it in less than 5 minutes).
We fully recommend it.
