We never actually met Anna or Silvia, but we were greeted by another man who was very nice and gave us a lot of very useful information. We needed to arrive late and although this was clearly inconvenient, Silvia and Anna were very understanding and did not charge us extra. The apartment was clean and cozy and very close to a tram station, allowing us to get to the island very easily. Although we never met Silvia, she sent a few messages to check in and make sure everything was okay. Overall, a great experience.
