An incredible city!
I absolutely love Sevilla - so much that I returned for another weekend a month later with other friends, just because I wanted to see it again! The city's architecture and environment is incredible, and embodies everything I think of when someone says "Southern Spain:" palm trees, yellowish-orange and white buildings, lovely weather, incredible-smelling air (sounds weird, but very true), friendly people, and excellent tapas. I can't recommend this city enough - if you ever get the chance, GO!
Insider Tip:Three friends and I went "tapa-hopping" on Alfalfa Street - order one or two tapas to share and a drink at one restaurant, pay, then do it again at another restaurant, then another, then another.... so much fun and not expensive at all! About 12 euro total for four places. Get croquetas, tortilla española, and queso manchego. Everything is delicious!
