You cannot go wrong with this property! It's only 2 blocks from the Historic City Center and a block from the Plaza Nueva (main square) where you can catch a taxi or the street car. It is also a block away from the main shopping district and a short 5 min walk to the Cathedral.
The property itself is very comfortable if you respect your privacy or travel with children and want to get away from them for a while. It has several levels with the main level kitchen, living and dining room on one and the bedrooms on another. There is also an elevator if you don't care to climb up the stairs.
There is a supermarket half a block away and a larger one within a 5 min walk distance. Plenty of local restaurants and well known American fast food chains are also within a 5 min walk.
I would definitely stay at this property again if I returned to Seville. I traveled in July with my 7 year old twins and their nanny.
