The basement apartment is modern and comfortable: large sofa, good bed. The cooking equipment is high quality. Our big gripe was the lack of hot water in the shower, as it turned cold after less than 2 minutes. (This happened twice; once in the evening and again the next morning.)
We loved the central location - a 10 minute walk from Piazza Maggiore and most other sites. It’s on a mostly pedestrian street that comes alive at night with dozens of restaurants and bars that cater to a mostly younger crowd, though we old farts felt comfortable as well.
