We had such a lovely stay at Sonia's place – the location is absolutely perfect as her place is so close to the metro entrance (only a couple of minutes walk) and the red metro line will take you directly to the Duomo and other places in the centre. The apartment is really beautiful too and Sonia is so welcoming, she gave us lots of great travel tips and info on the local area! We were in Milan in January and found the apartment to be lovely and warm even in winter.
