I had a great time at Rocco's apartement. It 's perfectly located (in teh center of the city, closed to bus, museums, shops) ,really clean and cut. Rocco and his wife were realy nice with us, our flight was late but they waited for us until we arrived.
Besides, they left for us a list with some restaurants, shops, museums we might like in the city.
A perfect flat for your stay in Milano !
