The flat is very well positioned and clean. It’s a safe area, 15 min way to the center, where the Duomo is, and 10 min to Navigli. There are many shops in the area too. The train and tram are also quite close (5min walk).
The two beds are quite comfortable. The one upstairs is a proper double bed. And the one downstairs is a sofa-bed. If you sleep on the side closer to the sofa back, it’s really comfortable, but the extended part is hell. So I would not recommend two people sleeping there.
The only problem we had is that we booked this flat wanting to use the kitchen to save some money (as we were travelling for work), and the cooker is induction, so it would not accept some saucepans they had. On top of that, the toaster was broken. But we told them and they immediately tried to find a solution, even though we only got to use the equipment one day. I hope the next guests will be able to use the whole kitchen with no problem.
