Agree with #1Of course it depends on your interests,but there is a lot to see and do in Madrid itself,and there are several very interesting day trips (even without Salamanca,which is a very long day trip for me...though a great place to visit).
Toledo,Segovia,Avila,El Escorial,Aranjuez etc etc

Would you recommend multi-day trips to Seville/Malaga/Cadiz considering I only have 7 days in Madrid.I suggest you do a bit of research first.
