Christ, we apologize however the months of July and August at the beach/playa is very busy because Cubans from all around Cuba take their vacations in beach towns during their holidays. Cubans like loud music, it's part of their culture, we can't change that. Outside of July and August La Boca is tranquil. As well, your tour guide should have advised that Cuba is a sub tropical destination, therefore very hot during the summer months. As for the water, we do apologize but we had some challenges that week with our water pump which we are fixing. As for the flies, when you are outdoors in the hot sub tropical summer months flies tend to be a part of the outdoors, in the kitchen where we could have served you if you liked we do not have flies, indoors and fans that keep the flies away. That being said, if you visit the beach again during the winter, spring or autumn it is very tranquil, quiet, clean water, and clean beaches. Hopefully your next tour guide will better advise you. Thank you for staying with us.
