This apartment is located in a quiet building and very close to transit (buses and metro) although many tourist sites are a walkable distance (from the unit). There is a grocery store located within a 5 minute walk and a large convenience store just downstairs. The apartment was clean, the beds were very comfortable, and each main room (bedrooms and living room) had air conditioning units with individual temperature controls (that worked well).
The apartment is basic, though. Some of the walls need a coat of paint. Two adjoining bedrooms have a translucent window that lets light shine through - an issue if the sleeping habits of people in each room are different. There is no 'house manual' (to reference) within the apartment that provides instructions, directions or general information.
(Nearby, is a great restaurant called Restaurante Cierzo.)
