We stayed in the apartment for 5 nights with 3 people.
It is super modern, you can tell it has been recently renovated. The interior is beautiful, and you feel straight at home. Alessio provides towels and shower essentials as well as welcome snacks and drinks. While the apartment is small for 3 people, this is no problem whatsoever if you are simply planning on using it for sleeping or relaxing in the evening. Additionally, there is a balcony with a covered seating area outside with a beautiful view of the Duomo of Milan.
The neighbourhood is nice, there is a supermarket two doors down and lots of restaurants in walking distance. The Colonne di San Lorenzo is very close, which is where you can find tasty restaurants (try the 12€ all you can eat lunch at the Asian restaurant Kobe!) and very cute and yet affordable clothing stores. Missori is the closest metro station, yet Milan is not that spread out and you can easily walk everywhere.
Alessio is a great host, he would get back to us immediately about any questions. Very happy guests here and if we're coming to Milan again, this is where we'll stay!
