Yes, they are free too!
Safes, TV with a bunch of channels no extra charge so you can see the weather brush up on your Spanish and Catalan! Catalan is TV3. Little mini-fridge. They charge if you drink the beer or eat the toblerone but they don't charge for the water. They also don't mind if you put your own drinks and food in the fridge. You CAN also control the AC and heat. Do watch out for the tub and shower -- lukewarm is warm enough, you won't be too cold and you'll avoid the hot blast people talk about.
