I have been travelling and staying using Airbnb in some places and countries, but I think Valeria's place is one of the best.
Valeria did not just offer a very comfortable private room but also her whole apartment to stay, so I finally knew why she said it is a penthouse.
The room itself located in the top of the classic building (7th floor) that offer a quite unique experience.

Location is perfect, just 5 minutes walk from Metro Subway (Gambara Station) which can lead you to any area in Milan City. It is not really in the centre of Milan, but in Milan what you need is the place that is close to the subway.

Valeria is a very nice person and host, she really took care of everything that her guest might need. She will help you to give any information you need about the city. Breakfast and water are provided, and even let me do anything on her kitchen. Thank you Valeria :)
