Most hotels charge a lot for breakfast.  If all you want is a Cafe con Leche (coffee) and a serrano ham hot roll (the Spanish version of a bacon roll) or toasted roll, sliced, with chopped tomato on, head for a local cafe, where a quick breakfast can be had for around 2 Euros.  There are several cafes behind the Cathedral (on calle Cannon) all with outside tables plus some indoors.  You'll see many locals having breakfast.  Don't be afraid the try out these local cafes - the less fancy they are the better the coffee seems to be.
