I was sold a holiday that didn't exist! (sadly, I was not the only one).
Especially when booking from Italy, you will find this Posada's bookings are handled by a company called JMB and a guy called Jacopo Biasion, the son of the (former?) owner of the Posada.
For unclear reasons, which are to be clarified in court, this person has taken the full payment from us and two days before the departure date he actually communicated that no accomodation would be available for us.
He then promised he would give the money back, given that we couldn't have what we paid for.
The money hasn't been returened as yet (2 months after the suddent cancellation) and we are now taking legal action against them.
If you are planning to go to Los Roques, stay away from this Posada and NEVER deal with these people.
If anything similar happened to you, please come forward and provide any useful information to secure these people to justice.
