Stefano was awesome. Super friendly, and his place was stylish and comfortable. Would definitely recommend.
Easy to get around (taking the #3 trolley straight to the duomo) and the canal at Navigli was an awesome spot for drinks and food (about a 15 minute walk or 5 minute trolley).
You’re right by a train line, but honestly, it’s not at all annoying/loud.
Also, when going to the cathedral, don’t stand in line at the main entrance. Buy a ticket (on the south side of the duomo) for stair access to the terrace+cathedral (12 euros), and enter the stairs on the north side. No line, plus access to the church after the terrace.
