Stayed at the Abacus hotel for two nights in May 2016 with 3 kids. Although not too fresh on the outside, the interior is up to standard. Clean, spacious rooms, sufficient towels etc. Breakfast outstanding. Free parking in the garage is convenient. Staff friendly. Wifi perhaps a bit slow. The location itself is of little merit, but with the subway (red line to Duomo) less than 100m from the hotel entrance, it is practically situated. Good value for money, recommendable.
