Hello shanellnumber5,
My suggestion would be: Wake up 8 a.m. or 9 and get yourself a breakfast of churros and coffee. Then head over to the Prado. At lunch, about 2, go try some tapas, morcilla and calamares. Take a walk in Retiro, which is very close to the Prado. Then take a walk to Puerto del Sol, and Plaza Mayor which is very close and sit outside and have a mirienda (snack) and a drink, or two.
Then I would take a nice walk to Plaza Espana. I would then take a small nap and then enjoy some of the night life, of which, I'm sorry to say, since I'm an early riser, I don't know too much about. I hope someone else can help you there.
If you don't feel like walking that much, buy a diez veces metro ticket.
