Looking at the map I did not find Anna's place so central. I was wrong. Not only that it's close to the public transport, the Garibaldi train station is only 20 min away (by foot). Anna provided us with great food for our breakfast. There is no real kitchen but frankly, who would like to cook in Milan??? :)
The place is big enough to spend there a weekend or so, as there is everything you need. When I got a blister from too much walking, I found plasters in the bathroom's cupboard!
The street is lively and there are many restaurants and shops very close. Even a big 24/7 supermarket.
I highly recommend Anna's place and I do hope her place will be available when I am back to Milan.
