I can't find enough good things to say, everything was excellent from start to finish!
Nice and beautifully decorated appartment, clean, tidy, and fully equipped. The shower tub was in a separate room from the bathroom, making it more convenient to use for a bigger group of people. The place was bright, easy to heat, and it felt safe. Also, it was in a great location, although not particularly central, and easy to reach with different means of transportation.
Stefano was a wonderful host, he and his family were always there to help us if any problem or question occured, and they made us feel like home. With Stefano, we had an amazing time, he picked us up at the station, and he offered to give us a little tour into the city and take us out for ice cream.
To sum up, I would happily stay again in this house, and I would recommend it to anyone who seeks a good stay in Milan.
