Please be sure to get explicit instructions on how to enter the premises, for whatever reason that information was missing for us and as a result we had to wait outside looking for a lockbox that didn't exist and finally communicating the entry steps with Lina the hostess. Put a real damper on our last night in Lisbon. Also, I'd inquire if the flat you're staying in actually has views of the water. Our flat faced the street. . .?
