Mariarosa was an excellent and gracious host. I had a super weird 10pm checkin. Then two days later, a 3am checkout. She had to wake up to lock the door. She was kind and thoughtful the entire visit. The apartment itself is eclectically charming. It is close to the green subway line and the main railway station was a 10 min walk. The red line was close-ish but to do the touristy stuff - you only need the green. I highly recommend staying with Mariarosa if visiting Milan.
