I did not get to meet Rosanna or Francesca, but they responded quickly when we communicated. They notified me that the boat stop near the place was closed and arranged to me to meet with Olga at the previous stop. The apartment was just as pictured, roomy and close to the main sights. She showed us around the apartment and gave us a lot of information on a map. The entrance to the apartment is independent from the others and there are stairs to climb if you have heavy luggage.
