The description of the apartment needs to be adjusted:
1- The title of this airbnb says that you do have beach access. There is no access to it as the door is permanently locked. There is no other way to reach the beach easily.
2- the apartment is at the level of a train track, right in front of you. It is noisy and not described.
Laura, the host, is adorable and super helpful. She will give you all the local tips.
