Céntriko Apartments are run like a small hotel. Key pads to get into the building and apartment (which was great, no worrying about losing/forgetting the keys).
Apartment was very clean, comfortable beds, kitchniette fully equipped, central AC was lovely and very strong. Great location, we were just minutes walk away from Alcazar and cathedral, and many of the restaurants and sites. We would stay here again in a heart beat. :)
