My stay at Bruno & Ros' place was really different from a typical b&b experience. It was much more like being a guest at some friends' home. Bruno and Ros are wonderful hosts, extremely kind and nice, and with a lot of interesting things to tell and teach, not only about Milan and Navigli, but about art, music, wine... and much more.
The apartment is beautiful, full of books and interesting things, clean and quiet. Location is wonderful as well: metro line is at 5 minute walk, and the neighborhood is full of life, bars, restaurants, bookshops...
