During the Welcome Days of Polimi I stayed at Vlad's home because it is super close to Bovisa Campus. Even if I arrived at 11pm I was able to check in.
Vlad showed me the flat with the kitchen, two bath rooms and the room where I was able to stay.
During the stay I was not too long in the room, but when I came home I always felt safe and it was nice.
There was no problem at all, everything worked and the communication with Vlad was super quick.
I'd go back there anytime!
