Plug sockets are Standard UK. TV is generally by Satellite so the TV works via the Scart lead input, your accomodation should already have a dish. You will need a sattelite decoder, for limited choice of English language channels you can by a box for about 40 quid from the supermarket and get CNN, BBC World and a number of free movie chanels. For a better choice you need a subscription, for instance one of the the Mozaic packages from QTel.
