I would only day trip to Cordoba, and maybe try to day trip from Madrid to Toledo, spending an additional day in Madrid and one less in Barcelona (that would still leave 5 days in Barcelona and give you a little bit more time in Madrid). I loooove Seville and think it deserves at least 3-4 days. And for Barcelona, 4 is the absolute minimum. Best of luck, it's so hard to choose!

Very nice granada hotel. I took a look at dates and a strange thing happened. If I try to book sept. 28, 2 nights. it is total 225 plus tax. If I book them separately, it is 90E/night plus tax. Make sure the same is 't happening to you.

I would not worry about the location. I did not check it on a big map, but granada is not that big, and taxis are inexpensive and good bus service.
