The flat is cozy and clean. Location is good for the price too, we usually walked to the center of Milan w/o transport and only got a tram or taxi when carrying luggage or returning late.
Max was not in the city during the most of our stay, but he provided detailed instructions and was available on phone to answer a couple questions we had.
Wi-Fi was rather slow (ADSL, 5-8 Mbit inbound and only 0.3-0.5 Mbit outbound), may be enough for relaxed web surfing but definitely not for cloud drives or uploading video to YouTube.
Everything else was fine.
