I'll start with what my Mom said: "This is the best Airbnb I've ever stayed in." Granted she was being a tad melodramatic, but we were impressed by the attention the hosts paid to make this a smooth and enjoyable stay.
The apartment is centrally located in a pedestrian-only area with all the major attractions within walking distance while being mostly quiet. Everything is clean and the kitchen is well-equipped.
Most memorably, the hosts were very helpful from the moment we booked the apartment. They gave us tips on the trip and booked a flamenco show for us. When we told them we were a bit chilly, Joaquin arrived with extra duvets and assistance with the heat in 15 minutes.
