If you are looking for a great place to stay in Milan that has excellent access to public transportation to the main tourist locations then you cannot do better than Antonio's place.
Antonio is terrific and an excellent host.
The 2 tram stop to the Duomo/Galleria/Las Scala area is just a few minutes walk away.
The Metro stop is a 8 minute walk.
Milan's public transportation is very logical and easy peasy to use.
