Federica's place is great. It's in a very convenient location, close to shops and restaurants. There's a great restaurant right on the same street, Colline Emiliane. Make sure to make a reservation ;).
There's a grocery store near by. Having a washing machine was really helpful. The apartment is on the 2nd floor (or 1st floor for Europeans) so not too many stairs, but there is an elevator which was great for our luggage.
The bathroom was good size. It looked like it had been recently redone, nice tile, big mirror/medicine cabinet. There is a metro stop not to far away.
We would definitely consider staying here again.
