Very clean, nice place with everything a traveller needs for a comfortable stay. Susanna is an excellent host, making sure nothing is amiss and that you feel welcomed in Milan.
The apartment’s location allows easy transport to the centre, but not the quickest. Many places were 45-50 minutes away by tram/metro, but as long as you have the time, it’s not a difficult commute. And there are plenty of local amenities very close to the apartment.
I would just say if you’re sensitive to noise, beware the apartment gets a lot of noise coming from neighbours — just the way the building is made! You can hear them walking, etc. But the area itself is very quiet and chilled.
