Luca’s apartment is about 15-20 min walk from the train station and about 4-5 subway stops from the downtown Duomo area. It’s a good amount of space and it was nice to be in a quieter neighborhood. The sofa bed isn’t very comfortable, but worked for the couple days we were there and Luca is great with communication and recommendations and checking to see if everything is ok. Definitely go to Pasticceria Martesana.
