I was travelling to Milan for work meetings in the September month and chose to stay with Serena.
Serena was a most warm and welcoming host - super friendly and happy to chat which I found great since I am new to the city.
The apartment was great for my needs staying only two nights, however the room is in a basement and if as a person you thrive on natural light it may not suit you. The room was clean and comfortable though very dark, and since the weather outside was blue skies and 30 degrees it was a shame for me.
