Carla is a very welcoming person and very reactiv in answering to emails. She gave us all the details we need. The apartment is very nice and very well equipped. Its size is perfect for a 5 person family.
The access is easy since it is very close from Piazzale Roma (pratical if you arrive by bus or waterbus) and even closer from the train station. It is ideally located to discover the city. We would highly recommend this address !
