Walter's apartment is a real home--it has all of the amenities as if it were your own place. We were pleased that there was soap in the bathroom, soap for the washer, etc. Plus, the kitchen is extremely well-appointed with equipment, spices, oil, etc. We stayed here with our two boys, ages 11 and 16, and they were comfortable in their bedroom with the twin beds.
The location is fantastic: about 15-20 minute walk to all of the important places: the Navigli, the Duomo, Brera, etc. Plus, it is only about a 2-3 minute walk to the Metro stop. We were able to use the Metro to the N. Cadorna station to take the Malpensa Express to the airport...very convenient.
Walter and his daughter, Margarita, were super responsive to all of our questions and needs. We would stay here again if we come back to Milano!
