The apartment of Andrea and Nicole is very nice with a traditional Italian decoration. We get a great welcome from Nicole - a nice Italian guy. He gave me an extremly warm welcome, as well as more valuable guides to visit around Milano. He also prepare carefully cookies, white wine, coffee, jam...
The place is also close to Milano Centrale (the main train station of Milano). We can walk around 15 mins to there. It also connects with the metro Station Sondrio of line M3 (just 5 mins by walk) where we can take the metro directly to Duomo - the most attractive sightseeing in Milano.
To sum up, if I can rate 10 stars, I will do. That is an extremly perfect accomodation in Milano.
