We stayed a couple of days in Carmela's apartment in Milan. Her place is a few hundred yards from the Duomo, which is the cathedral and the major shopping and eating place, and also has all the Metro stations that let you connect to Milan Centrale and the Malpesna Airport.
Carmen was there in person to welcome us. Her place itself is very stylishly done, with objects d art all around, and a full stack library corner. We loved how she left a full breakfast of croissants and biscuits for our children (she had checked with me a few days earlier as to what the children liked for breakfast!)
Would recommend this place highly if you are going to be spending a few days, as a couple or with family.
