We stayed at Roberto's place in Corso Como. The location is obviously outstanding - we were literally in front of 10 Corso Como, a minute away from Princi and Eataly, not to mention the new developments in Isola. And two minutes away from Stazione Garibaldi, which means we arrived - train-to-door from Milan Central Station in about 12 minutes. Amazing!
We were pleasantly surprised that the apartment was quiet (overlooking a courtyard) and with lots of special touches (there was even a Panettone for us :) . Also, Roberto's hospitality was remarkable even by AirBnB standards - he met me for the key handover, and because we only could arrive a day later than we had planned, he graciously added an extra day for free.
Certainly a place to return to, and definitely one that you should stay at, too - if you get the chance :)
