Will definitely help if you speak Spanish. Very little communication with hosts so not good if you need help with the locality in terms of public transport in the town, recommendations for restaurants, etc. The massage promised never transpired. Good location and nice accommodation (no tv, radio etc) but sound carries inside these types of accommodation so not good if you are loud!
However we did enjoy Seville and it was a good place to be based (about 20 mins walk to centre), streets VERY narrow so always to be careful of cars, motor bikes.
Accommodation has everything you need - nice bathroom.
