This was a great apartment and Pablo and his mom where great hosts.
On the day of my arrival, I was greeted by Pablo's mom who was very kind and resourceful. She gave me directions to the supermarket and the subway, and some hints as to where to do shopping nearby. Pablo communicated with me via SMS prior to my arrival and made sure that everything run smoothly. He also made himself available by SMS but there was no need to communicate again as the apartment was perfect.
The apartment is just as it appears in the pictures or perhaps even nicer. It is a nice, clean, spacious, modern and comfortable studio that has everything one needs for a pleasant stay. The location is very convenient, just a few blocks from the Central train station and two blocks from Sondrio subway station which is only four stops from Duomo station (the center of town). I definitively recommend Pablo's apartment and will no doubt stay again there if when I return to Milan!
