We felt really comfortable at Aurelios flat. It was really close to the train station and has everything for the daily life in the neighborhood (supermarket, restaurants, metro..).
The flat was big enough for us 3 over weekend and offered everything what we needed. During the night it was a bit cold (we couldn't find the heater), but that was not such a problem.
The best: at the check-out day we could store our luggage till 5 pm in the flat and grab it just before leaving milano.
We recommend the flat to everyone and would book it again when returning to milano :)
