I stayed at Enrico's for 3 nights and had a wonderful time. The location is great, just around the corner from a metro stop with great ease of access to Milano Centrale and the Duomo, as well as other parts of Milan. As I was traveling alone the location was important to me, and I felt close to everything and safe, even when returning quite late at night.
Roberta (Enrico's wife) was always friendly and on hand to help with anything. The decoration of the flat was a lovely touch, and the flat itself was very bright (even in the less than ideal weather!) and felt bigger than it actually was. As a solo traveler it was perfect.
I would recommend this flat to any solo traveler planning on spending time in Milan. Enrico and Roberta are wonderful hosts.
