Adriano and Nina are both very kind. They're apartment is nice, super clean and located just outside the walls of the old city center. It's simply great they offer their bikes to us, because it's really the best way to get around town. Sevilla is nice and flat, but mind you; there are not many bike lanes, and many streets are oneway. So, before hopping on the bike, please note a little common sense and experience biking in large cities wouldn't hurt one bit. Recommended!
