I've got a week in mid-February, and am itching to return to Spain or Portugal. I've been to Madrid, Barcelona, Seville, Ronda, Cordoba, Grenada, Toledo, Segovia, and Lisbon, Salema, Sintra, Coimbra, Guimares, and Porto. Any suggestions? Flying out of Boston, love doing public transportation (in other words, prefer not to rent a car), so buses and trains are fine. I'm curious about Bilbao, Caceres, Zaragoza, and wouldn't mind returning to Seville.
Any and all suggestions would be appreciated!
