What a fantastic stay at Luisa's place. The room was spotlessly clean and larger than expected. The private bathroom next door was just the same. Luisa is a lovely host - friendly, helpful and very accommodating. Luisa sent over instructions on how to find the place beforehand and it's a short metro ride and then a short bus ride (the 54 bus runs frequently) from Centrale. I bought the 3 day Milano travel card for 12 Euro which served me well. This is well worth the 5 stars. I can strongly recommend Luisa's place for staying a few nights in Milano.
