Alfonso lives in the same building and was extremely helpful and available to us during our stay. The apartment was the nicest we stayed in while in Spain and was comfortable, modern, and very nicely furnished.
The location was good and a short walk to lots of great shopping and great restaurants at the Plaza Mayor. But if you're looking for a nice view from the balcony it's not there--you are across the street from a school building. On the plus side, this made for nice quiet evenings without a lot of street noise which is so common in Spain with late night diners and party goers hitting the streets after midnight.
