Userful information
The Euro is the legal currency on the Canary Islands, as in the rest of Spain. The local time zone isGreenwich Mean Time, and GMT plus one hour in the summer, thus making it an hour less than in the mainland of Spain, the Balearic Islands, Ceuta and Melilla. The decimal metric system of seven basic units is used for weights and measures and electric devices function using 220 volts. Plugs follow the European system of round pins. Even though water supply and quality is guaranteed by the public network, as in the rest of the country, bottled water consumption is very common. All well known and important bank cards are accepted in almost everystore.

Claims can be registered at the tourist establishment, at the tourist information offices and at every registry of the local, autonomous or national authorities. Claims and complaints are studied and, if they are well founded, companies are imposed an appropriate sanction.
