Filiberto and his associates were very good to deal with.
We stayed at Settala for one night (the last night of our trip) due to its proximity to Centrale and the easy access to Malpensa.
Since we stayed only one night we weren't too fussed about the location - 4 metro stops from Duomo, and not a whole lot nearby.
When we return to Milan we would stay somewhere closer to the action.
