I highly recommend staying at Letizia's apartment - it was nice and spacious, with a ~15 minute walk to the centre of the city (and tram and subway stations are very nearby). The place has a great balcony and is very clean,. Letizia was a very good host - she gave us tips for visiting the city, gave us her restaurant recommedations and she was very responsive. We spent a great night in Navigli thanks to her tips :) The nearest bakery, shop, pizzeria and gelateria are just outside the building.
