Lin is a great host. Her flat was super clean and close to Milan downtown. She was really nice and helpfull, I stayed there in new year's eve and there were changes in the schedule of public transportation, she made sure to send me those information a week in advance and even during my stay whenever she heard about any other news in the city, she made sure i was aware. I highly recommand staying at her flat and i would stay there whenever i come back to Milan.
