I would definitely stay there again, visiting Milan.
The flat is not located in the center of milan and chose it, because it was near the sports venue I was visiting - but Metro and Tram nearby are going directly to the Dome of Milano in a few minutes. Tram takes longer, but it's more fun. There also are some very good restaurants for dinner nearby which are no tourist-traps, but rather good italian food.
Martha herself was very helpful with lending me a bike and with many tips for everything and I really enjoyed her company!
Of course it was very clean, which is important to me and I loved the cosy bed on the gallery.
Thanks again!
