Overall assessment of this airBnB host: VERY POSITIVE.
PROS: Antonella is a nice and kind host and welcomed me in her flat not far from "Vittorio Emanuele" (or "Manzoni") metro stop; the flat was small and essential (with a small toilet with an electric flusher) but for the price I paid I would say reasonable; the flat was clean.
CONS: there were no shutters for the window but a red curtain, which made light enter in the morning (but the silent neighborhood helped me to sleep, so overall OK).
