We paid 546 for 4 nights and 20 for late arrival. That didn't get us anything stunning. A smallish under the roof apartment that was redecorated too long ago and smelled like sewer for too long. A nice view. Close to the metro station. Spots on the sofa and walls. Clean and modern kitchen. stranger hair around the place. books to read. Very quiet. The elevator is tricky, you have to climb an extra floor from where it let's you, and it can stop working, which is not good when you're on the 7th floor.
i had to reboot the internet router at least twice a day to make it work. the host said at my suggestion they'll arrange to have it replaced. never came back and they won't do it in the future either. It's not luxury, it's like a friend's apartment you get to stay in while he's away. It's Milan, I know, but i would not recommend it.
