This apartment wins best shower award during our travels in Spain - hot water was plentiful and the bathroom was lovely. The whole apartment was very nice and we were really comfortable. AC worked well on hot afternoons, which was important to us. Gary was very communicative and flexible, which we appreciated.
The location is nice, about a 10 minute walk to the cathedral and Alcázar, and about 20 to the Plaza de España. Gary's recommendation for tapas - Bodega Santa Cruz, La Columna - was fantastic. (The food was deliciious and cheap and it was a very authentic feeling experience. Go before prime time if you care about sitting down, otherwise crowd in at the bar and enjoy.)
There was a lot of shopping in the areas nearby.
