We loved staying in Arianna's flat! My friend who lives in Milan met with Arianna's brother who was so kind to show him around the flat and explain everything in fine detail and guide him trough the flat and the area.
The flat itself was actually bigger and nicer than from the photos (apart from the bathroom, which is very small but charming), and we loved the furniture and decor of the place, it felt very comfy and familiar. The flat is small but has all 2 people need for few days stay.
It is very clean, neat and nothing we needed was lacking.
The neighbourhood is safe and pretty, close to a very nice park (piazza Libia), has a supermarket across the building (not open on Sunday, but there is a Costco close by). Nice walk to city centre towards Porta Ticinese.
We would definitely recommend the flat to anyone wanting to have a nice and warm stay in charming Milan flat.
