Stayed at Jhonny apartment Oct 2022 for one night. Had a really great stay the flat is in a great location a 5-10 min walk to the cathedral and Piazza del Duomo where there's lots of restaurants and bars.
Apartment was very clean, stylish and felt very spacious as well!
Jhonny was a great host arranging an early check-in for me and great communication always replying within 30mins.
As others have mentioned is up quite a few stairs so definitely bare that in mind
