We had a nice stay here during our week in Milano. The apartment was very modern and clean. Felt very much like a proper hotel room. The airconditioning worked wonders and the bed was big and comfortable, resulting in good sleep every night. There was almost no sound from the traffic outdoors when the windows were closed, and even though you could occationally hear the neighbors, it was never a problem.
The location of the apartment is very close to the central station så getting on the train and around the city is a breeze. But this comes with the consequence of being close to a city centre, there are definitely some pushy and loud beggars/homeless people around the city, especially at night. Though this will be the case in every big city centre around the world, and this apartment is far from the worst I have experienced.
Overall a nice stay and we would definitely recommend if getting on the train at centrale is first priority.
