Margherita was very prompt with correspondence before and during trip. Only small check-in 'glitch' is unit is #72 (not #11 per Airbnb), but easily solved with a phone call.
Unit is very clean, room is large, double bed comfortable and shower/toilet spotless. No lock needed on room as Margherita is the only other occupant.
In Milan centre in ~25mins (10min walk to tram, 5min wait and ~5-10min tram).
Recommend Margherita's unit if you want pretty close to centre, quiet and secure neighbourhood !
