Our family of 4 loved this place (kids 15 and 12). The place was clean and stylish. Location is great- 2 mins from the metro. There is a little place next door for morning coffee and croissants.
The 1.5 bathrooms were modern plus there was a washing machine. The building was very secure. Apt is on the 2nd floor which was fine.
Valeria was very helpful with any questions. We would definitely stay there next time we visit Milan.
