very well located apartment (5min walk to Duomo and to bus 73 direct from/to Linate airport), bright, very clean and well equipped (incl. everything needed in q kitchen + bathrobes, slippers, soap, etc). the concierge was available at all times online and helpful.
the only minuses are the nearby main street noise and the AC which is not very powerful. still overall a very good bargain. just take earplugs and skip if you absolutely need cold nights.
for luggage storage after checkout and until your flight, you can ask the nearby California Bakery shop (against minimum fee), where the food is also very good.
