The apartment was exactly the same as pictured and described in the listing–except that it doesn't have a dryer but rather a retractable clothesline. The place was very clean and very well kept. Half-way into our stay, the cleaners came and tidied up and changed the linens.
The location is perfect, it is virtually 10 minutes away from everywhere: carrefour market, Sol, Museo Reina Sofia, and Atocha Renfe station. The metro station is about 20 meters from the building's entrance, and there are a lot of bakeries, cafés and restaurants in the vicinity. Nuria was very responsive, and promptly helped us when a minor problem occured with the plumbing.
The apartment was small but it accommodated 4 adults very comfortably. I would stay again there in a heartbeat.
