I love Sevilla. I have traveled extensively throughout Europe and Sevilla and Spain are definitely my favorite places. You cant beat the culture, nightlife and friendliness of Spaniards and Sevillanos. Its an amazing city with lots of rich history and tons of things to do.
Insider Tip:I really enjoy going to the maria luisa park, partying on calle betis at night (dont go before 2 am anywhere in spain), the new tapas market on the sevilla side of the triana bridge, and walking through the quiet streets of Triana, my favorite neighborhood in the city.
