I had a very nice stay at Silvana's apartment. It is well equipped with all the things you need (dishes, TV, iron, washing machine etc..) and very clean. Although it is located more on the verge of Milan, the city centre is very easy to reach by the metro (~20 min). Very close to the apartment you can find the most important places (e.g. grocery, bakery) too.
Silvana is a very courteous host, showed me some places at the first day and was open for all requests I had.
I just can recommend Silvana's flat for a trip to Milan, even if you want to stay a longer time!!
