We had a good stay at Lucia's place; her husband could hopefully receive us late on friday (we had problem at te train station.. Sorry again for that).
Very kind. The appartment is comfortable. A bigger coffee maker would have been nice ;-P and the toilet flush should be refixed but these are the only things. We did not have lunch or dinner there.
You need approximately 40-45 min to reach the Duomo and the expo. Well desserved by bus.
I would recommend it. Thanks again.
