Pros:
The apartment is very beautiful and spacious.
The wifi works well.
The location is good, with a metro one minute away and only 20 minutes away by foot from the Duomo
Cons:
One must pick up the keys in an office 10 mins away form the train station. If you have bags this is rather annoying. Much more so if you're coming from the airport.
This office does NOT offer luggage storage
There is mold in the bathroom.
