I was assigned to the Castle building, there is no WiFi, it is veeery noisy, you can hear the noise from everywhere.
The guy who assisted me at the registration was kind of angry, sad, bad mood, I could not tell, but the way he talked to the customer was not polite. He is one of the natives from the island, however, there was a young tall guy very polite and nice when helping or responding to questions. It is a great location though.
