Overall, this apartment was probably my most disappointing experience in my 3 week stay in Italy. It was was quite dingy, and missing basic goods and appliances. For instance, there was no soap, toilet paper, or any other toiletry. The towels were super old and dirty. The kitchen didn't have any bowls. On multiple days, there was no hot water in the bathroom. The main apartment door has to be unlocked from the same side that it is locked. And Paola completely forgot to tell me about this major issue. It ended up with my family being locked inside one day when I locked the door from outside and left in the morning.
There were several times when i tried to text or call Paola and she was always very hard to reach. She did not show up for the check-in, and sent her mother instead, who was 20 minutes late and didn't speak English, making the check-in that much harder.
On the bright side though, Brera is a really nice neighborhood. It is great to eat, shop, and walk around. Lots of things are pretty accessible by a short walk.
