Parking in the city
If you want to rent a car I do recommend a very small one - it's easier to park and much easier to navigate through the streets. Keep in mind there are parking problems if you are looking for a free space. I should say more about parking - it really is a pain in the ass in most of the center and Sevilla has a problem with double parking. You can't live here long without noticing some poor soul who is blocked in and has no other option but to hit the horn every 30 seconds until someone runs up and moves his car so the guy can get out. On a weekend night people come to the center looking for nightlife and double parking in some places is very, very common. There is even a custom to leave your car locked, but in neutral with the brake off. Now if someone needs to get out from behind you they can nudge your car over until they have enough room to leave. Why all the double parking and half hour searches for a free space? Parking garages or paid spots are expensive since they have eliminated the cheap parking next to the river. Remember to never keep anything in your car if you are leaving it somewhere or anywhere. Rental or out of town tags are like a neon sign asking for your car to be robbed. I've seen cars with back seats folded down and the glove box open so the would-be thieves could see there wasn't anything in them. I've also seen "Soy de Sevilla" ("I'm from Seville") signs in cars for those hoping not to have their car broken into. So paid parking is expensive but can also be a nice security feature, so if you want to locate a parking space I recommend going to lanetro.com and using the callejero feature. Enter the address of where you will be and look for the blue "P" signs on the map to locate public parking - garages or lots. They even have an English version. Public garages charge anywhere from 12 - 19 Euros per day.
