The apartment is really cosy and clean, and very close to the ships stations, so the connection to the inner island of Venice is really great and available at all hours! Even though we didn't actually see Manuela, we always were in connection with Chiara, her friend and co-worker picked us up at the train station and helped us a lot with the Vaporetto Tickets and even gave us a very good introduction of Venice, with all kinds of things to do and a list with the best local restaurants!!
So all in all, the communication was satisfiying and the stay was perfect. Would definitely advise it and come back again!
