The Ibis Budget Hotel in Seville is extremely good value for money. We managed to park outside in the road for no cost. It was possible to take a no.28 bus from a nearby stop, all the way into the centre of Seville for 1.40 euros.
The hotel staff were very helpful and the rooms were quiet and air conditioned. It was all spotless. If you don't fancy an Ibis meal, there is a good local restaurant down the road on the opposite side, serving very tasty Spanish food at a reasonable price (12.50 euros for 3 courses). The breakfast at the Ibis was OK for 4.50 euros.
