The apartment is fantastic and very clean. It has all the required amenities and is suitable for a short stay in Milan.
The apartment is on a main road which can be noisy at times, but this didnt affect our stay too dramatically.
A walk from the apartment to the Duomo takes roughly 35 mins, but you can use the metro as there is a station 5 mins away and the ticket prices are affordable.
All in all, pablos apartment is perfect for a few nights in milan and would definitely recommend.
