I had the most wonderful time at Federica’s place. Everything is just as described but better. The flat was very cozy and clean, with everything you need. There is plenty of closet room, living space, and cooking space for one person. The view in the courtyard is very peaceful and the location is absolutely perfect. You are walking distance (10mins or less) to a main metro stop Repubblica, a lovely park called Montanelli, the neighborhood Porta Venezia (which has lots of cafes, bars, restaurants, and shopping), Chinatown, Corso Como, Corso Garibaldi, and Brera.
It is not mentioned in the description that there is also a doorman/lobby guardian of sorts who is very kind and adds to the safety of the building and ease of getting packages (really essential if you stay long term).
Federica herself is a fantastic host. She is very kind, helpful, and has great with communication. I stayed for 2 months and had no problems whatsoever. It was a dream stay!
