We spent two nights an Bruna's place. It's located conveniently near the Navigli area, where there are lots of nice bars and restaurants. To the city centre it takes about 15 min by metro. The room is clean and has enough space for two people. The rest of the apartment, however, is rather chaotic and messy and the bathroom appliances are not in very good shape. Also, Bruna smokes indoors. There's a small dog, but he's very quiet so you barely notice it. Bruna is a nice person who provided us with useful maps, leaflets and information about things to do in Milan.
