We had a wonderfull stay at Luca's flat. I strongly recommand it if you're planning on staying a few days in Milano !!
The flat was clean and well furnished. It's not located in the most touristic area but very close to the metro station so you are very close to everything. There is also a lot of very nice restaurants near.
The only down sides are the wifi which was really slow and the noisy street. It's really hard top sleep with the windows open because there is a lot of trafic noise but overall it was a very good time.
