Marcella is a really good host. She is very responsive and gave us all the details about her place. She is really kind to let us check in earlier than the scheduled time.
Her apartment is at level 5 but there's a elevator if you have heavy luggages.
There is a bus stop just outside the apartment that takes you to Duomo. You can get the bus ticket at the newspaper store near by.
I had a pleasant stay at Marcella's.
