We have stayed at various apartments in this area and this is the quietest one we have found. It is conveniently located in a residential block just along the road from the Matadero and the river with lots of shops/restaurants nearby.
Bus stops are almost outside the front door and a short walk to the nearest Metro station.
A ground floor apartment with a step down into it from the inner courtyard. Kitchen had everything we needed. We needed the heating on early in the morning in February.
A great stay - thank you Javier
